What is the definition of isotope


A molecule that has extra or less neutrons this changing its behavior. Eg Trillium is helium with a spare neutron, and is radioactive where helium is not.

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.

How many atoms of hyrdrogen gas in tow moles how


Hydrogen gas is a diatomic substance: Each molecule contains two hydrogen atoms.
A mole of hydrogen gas contains 6.02*10^23 hydrogen molecules, but since each molecule contains 2 hydrogen atom you have 2*6.02*10^23=?
The formula for nitric acid is HNO_3. It contains 5 atoms regardless of the elements
Now, 0.25 moles contain 0.25* 6.02*10^23 molecules oh nitric acid, ans since each molecule contains 5 atoms then 0.25 moles contain 0.25*5*6.02*10^23=? atoms
0.25*1*6.02*10^23 of hydrogen atoms, and the same number of nitrogen atoms and 0.25*3*6.02*10^23 oxygen atoms.

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.

Ionization


Please restate as a question. Do you mean "what is ionisation?" If so: ionisation is the physical process of converting a molecule or atom into an ion by adding or removing charged particles such as electrons or other ions, to form a charged form of the atom or molecule.

Brian Power Question? Five Associates stray off course during The Expedition and find themselves in a new Quest where there is nothing but a pile of molecules and the Avatar. Exhausted from playing all...


Every associate leaves 4/5(n-1) molecules of a pile of n molecule. This result in an awful formula for the complete process (because every time one molecule must be taken away to make the pile divisible by 5):

4/5(4/5(4/5(4/5(4/5(4/5(p-1)-1)-1)-1)-1)-1), where p is the number of molecule in the original pile, must be a whole number.


The trick is to make the number of molecule in the pile divisible by 5, by adding 4 molecules. This is possible because you can take away those 4 molecules again after taking away one fifth part of the pile: normally, 4/5(n-1) molecules are left of a pile of n molecules; now 4/5(n+4) =4/5(n-1) +4 molecules are left of a pile of n+4 molecules. And because of this, the number of molecule in the pile stays divisible by 5 during the whole process. So we are now looking for a p for which the following holds:


4/5×4/5×4/5×4/5×4/5×4/5× (p+4) = (46/56) × (p+4), where p is the number of molecule in the original pile, must be a whole number.


Therefore, the smallest (p+4) for which the above holds, is 56.

So there were p=5 power 6 - 4 = 15621 molecule in the original pile.

Which particle is the hightes in the following


Protons have a +1 charge. This is the same magnitude of an electron but an electron has a −1 charge. Neutrons have a 0 or no charge.

The following Wiki Article explains the process of Proton decay

Main article: Proton decay Protons are observed to be stable and their theoretical minimum half-life is 1036 years. Grand unified theories generally predict that proton decay should take place, although experiments so far have only resulted in a lower limit of 1035 years for the proton's lifetime. In other words, proton decay has never been witnessed and the experimental lower bound on the mean proton lifetime (2.1×1029 years) is put by the Sudbury Neutrino Observatory.[5]

However, protons are known to transform into neutrons through the process of electron capture. "When a high energy-proton collides with an atom, it causes the ejection of an electron from the outer layer of the atom."[6]:125 This process does not occur spontaneously but only when energy is supplied. The equation is:
1a11b43084f71df3683387ac7281c27b.png where
p is a proton, e is an electron, n is a neutron, and νe is an electron neutrino The process is reversible: neutrons can convert back to protons through beta decay, a common form of radioactive decay. In fact, a free neutron decays this way with a mean lifetime of about 15 minutes.
