Looks like homework to me and you should look on wikipedia for atomic orbitals and electron configuration for elements. or search google or visit your local library

For example antimony element 51
Electron configuration [Kr] 4d10 5s2 5p3 Electrons per shell 2, 8, 18, 18, 5

How are protons organized ?

Atomic protons? The nucleus of the atom of each stable element has a certain number of protons, and except for hydrogen, also neutrons. These numbers are what differentiate the elements and give them properties, whether gaseous, metallic, alkaline, reactive or inert. Protons have a positive electrical charge.

The number of electrons will match the number of protons to give a stable atom a neutral net charge. An atom which loses or gains an electron or 2 is known as an ion. An atom which gains one or more neutrons is known as an isotope. However ions and isotopes still have their proper numbers of protons.

Ions will seek to attach to another particle so as to gain stability. Isotopes will decay over time, sometimes thousands of years.

All the elements are arranged in families or groups where chemical properties are comparable, in the Periodic Table of the Elements

How are protons organized?

Atoms are the basic building blocks of everything around us. They come in different kinds, called elements, but each atom shares certain characteristics in common. All atoms have a dense central core called the atomic nucleus. Forming the nucleus are two kinds of particles: protons, which have a positive electrical charge, and neutrons, which have no charge. All atoms have at least one proton in their core, and the number of protons determines which kind of element an atom is. For example, an oxygen atom has 8 protons. If you were somehow able to change the proton number of this atom to 7, even if everything else remained the same, it would no longer be an oxygen atom, it would be nitrogen. For this reason, we list the different elements by their proton, or atomic, number. The periodic table of elements is a chart of all of the elements that have been discovered so far, in order by their atomic number.

What is the atomic number of Eieinsteinium trioxide

The atomic number for that element is 99. You did not pick an easy one to do. That element is man made. If you are mixing it with an oxygen molecule to get o3 compunds you are looking at a pretty complex structure.

What is matter?

Matter is a substance that has inertia and occupies physical space. According to modern physics, matter consists of various types of particles, each with mass and size.
The most familiar examples of material particles are the electron, the proton and the neutron. Combinations of these particles form atoms. There are more than 100 different kinds of atoms, each kind constituting a unique chemical element. A combination of atoms forms a molecule. Atoms and/or molecules can join together to form a compound.
Matter can exist in several states, also called phases. The three most common states are known as solid, liquid and gas. A single element or compound of matter might exist in more than one of the three states, depending on the temperature and pressure. Less familiar states of matter include plasma, foam and Bose-Einstein condensate. These states occur under special conditions.
Different kinds of matter can combine to form substances that may not resemble any of the original ingredients. For example, hydrogen (a gaseous element) and oxygen (another gaseous element) combine to form water (a liquid compound at room temperature). The process of such combination is called a chemical reaction. A chemical reaction involves interactions between the electrons of the atoms, but does not affect the nuclei of the atoms.

I hope you find it very helpful. Best regards.

What is the electron dot diagram for nitrogen

The electron-dot structure (also known as the "Lewis dot structure") for N is shown below:dubblea_6.jpg The red dots represent electrons that comprise the atom's 5 valence electrons. Recall that the valence (outermost) electrons are those that are involved in chemical reactions of bonding. The rule you should apply to drawing this electron dot structure is to first draw (or imagine) a rectangle around the atom's symbol, letting the rectangle represent the atom's core electrons (not shown), those within the atom's inner (s) shell. Then place one electron on each side. That leaves the remaining electron to be placed on one of the already occupied sides to give the electron pair.

It doesn't matter what side you place this 5th electron, because the final result is the pattern shown above, 3 single dots and one pair of dots, which neatly reveals the bonding power* of N (3) - and the existence of the one electron pair, which predicts special types of reactivity you will probably appreciate in more advanced topics of this element's behavior.

*The single electrons are more reactive than the electron pair, and will readily form bonds with other atoms, such as H. This allows you to predict that N and H atoms will combine to form NH3.

How do you know there are 5 valence electrons? For the answer, refer to the following partial image of the Periodic Table of the Elements I drew using Word and SnagIT software:
Notice the number-letter labels above each column ("group") of elements, for example "5A." The letter A indicates the groups of "representative" elements, the most common elements studied in general chemistry courses. The numbers before the "A" represents the number of valence electrons surrounding each element's atoms. For example, hydrogen has one valence electron, nitrogen has 5 valence electrons, and oxygen has 6 valence electrons.

Using the rules described above for drawing electron-dot structures, how many single dots and double dots should be drawn around H? Around O? Can you predict the bonding power of each of these atoms? What molecular compounds do you predict would be formed from the reaction of H and H? What molecular compound do you predict would form between combining H atoms and O?

Reactions tend to occur that cause the single electrons (dots) to pair up. This occurs because paired electrons are much more stable than single electrons. A strong driving force for a reaction is the going from a less stable state to a more stable state. Hydrogen atoms from H2 molecules (diatomic molecules). H and O atoms combine to form dihydrogen oxide, also known as water!

  • A very simple set of rules allows you to predict the electron dot structures of the representative elements.
  • The electron dot structures are very useful, because they can allow you to predict the bonding power of each representative element.
  • They are also useful in guiding your prediction of the compositions of molecules that can form during reactions between their atoms (that is, how many of each element in the molecule).
  • In more advanced topics you will also be able to use electron-dot structures to predict the shapes (or geometry) of molecules, including bond angles!
  • So, learning the skill of drawing electron-dot structures is very important to mastering chemistry!

How do atom the smallest particles of matter form


The current view is that atoms are made up of protons and neutrons (which in turn are made up of quarks and gluons) and electrons. The protons and neutrons are at the central core called the nucleus, and the electrons revolve around it, being held in orbit by the electromagnetic force between the negatively charged electrons and the positively charged protons in the central nucleus. It is very much like the solar system with the sun at the center and the planets revolving around it. They were formed right after the "Big Bang" when our known universe originated from pure energy some billions of years ago. The energy was converted to the elementary particles (quarks, gluons, leptons etc...) from which protons and neutrons were formed. From these, atoms of different elements were produced.

Hope i helped you.

I need to know what a nucleus is

The nucleus is the very dense region consisting of nucleons (protons and neutrons) at the center of an atom. Almost all of the mass in an atom is made up from the protons and neutrons in the nucleus, with a very small contribution from the orbiting electrons.

What the relationship between the proton number and the element 1 dentity

The number of protons in the nucleus of an atom is labeled Z.
Atoms with the same Z (istotopes) have the same chemical properties. So you cannot differentiate between them on the basis of their chemical properties because they all react the same way. From a chemical point of view they are the same element. They all receive the same chemical symbol. Knowing the Z number of an atom is equivalent to knowing the chemical element. One Z, one symbol. In short, if you know Z, you know the chemical identity of the element.

Hope it helps.
