What subatomic particle cuase the Atomic number to change


Proton How does the atomic number that is assigned to an atom change An atomic number assigned to an atom changes when the number of protons in the nucleus of the atom changes. By definition, the atomic number of an atom is the number of protons in the nucleus of the atom.

How many protons and neutrons and electrons in iodine


Iodine has an atomic weight of 126.9, comprised of 53 protons and 74 neutrons. It also has 53 electrons, because the number of electrons will always match the number of protons. The electrons are arranged in shells containing 2, 8, 18, 18, 7 electrons, totaling 53.

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

Would changing the atoms in water would it separate from what is attached.


Changing the atoms how? It takes a lot of energy to do that, and afterward it is not water anymore but some other substance, oxygen and hydrogen.

You can change the arrangement of molecules in water, when you freeze or evaporate it though

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.

Manual for SkyScan atomic clock -model 86742 I need to know how to change the clock to eastern time.


Hello

The SkyScan ATOMIC Clock

With the Skyscan Atomic Clock, you have the most accurate timepiece within the continent. It can receive the time signal transmitted by the National Institute of Standards and Technology (NIST), which is regulated by 3 atomic clocks and deviates less than 1 second within 3,000 years. The NIST broadcasts the time signal (WWVB, 60kHz) continuously from Fort Collins, Colorado. This signal can be received anywhere in the continental USA that long wave (AM) radio reception is possible with a portable radio. It is expected that the signal can cover a distance of over 2,000 miles from the transmitter. Therefore, your clock will receive the signal within the broadcast range anywhere an AM signal can be received; generally the signal cannot be picked up in massive metal and concrete structures unless near a window. In addition, some environmental effects (see next page) may affect the transmitting distance.

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.

A compoud made of A and B crystallises with A atom at the corners of the cube and B atoms at the face centres.Determine the molecular formula of the compound?


> cube

That implies 8 atoms of A.
Each atom of A binds to 3 other atoms of A, and binds to 3 other atoms of B.

> faces

That implies 6 atoms of B.
Each atom of B binds to 4 atoms of A.

So, you have A(8)B(6).

G-Shock Atomic Solar watch - ERR in atomic time keeping


The watch will set itself at specific time set times, this is likely to be at 0200 0400 and 0600.
You will however be required to set the time zone, the switch is likely to be on the back.
INFO:
Atomic Time Synchronisation:
How does it work.
SHORT VERSION:
Radio set clocks and watches receive a 60-kilohertz, radio signal from the NIST the official timekeeper for the US and is located in Boulder, Colorado. Ft. Collins. they use atomic clocks and transmits this official time via high frequency short-wave and low frequency AM radio signals, satellite transmission, Internet, and via telephone.

Setting atomic receiving mode


There are two three-bar displays on this watch.
The three in the top left will always show only one bar (or possibly no bars).  The top left indicates the level of charge in the battery and not the atomic receive function.
The three in the bottom right are related to receiving.  The atomic receive is controlled from settings.  With the time displayed, hold down the ADJUST button for several seconds.  Once the timezone name (e.g. LAX) starts flashing at the top, release the ADJUST button and press MODE once to get to the DST control. Press MODE again to get to the Atomic receive control.  Use the receive button to switch ON->OFF->ON... Press ADJUST twice to exit settings mode.
