if a number can change randomly it is called a variable
do you mean math equation? If you add a number to both sides of an equation you do not change it. That is called algebra
1.34 x 10 to the 6th power. And it is called scientific notation ... not number. 1340000 is just as scientific as 1,34 million.
VARIABLE. When this variable has a fixed number assigned to it and does not change, it is called a "fixed variable".
You can change your number in your settings. Go to your settings and press phone. Then press my number. You can now change your number.
No numbers change unless something happens to them. They are just called "numbers."

The only way to change the number of protons in an atom is with a nuclear reaction.
Ionic imbalance.

The common ratio.
It is called periodic law.
A sudden change in chromosomes is called a chromosomal mutation. This can involve alterations in the structure or number of chromosomes. Examples include deletions, duplications, inversions, or translocations.
The atomic number is determined by the number of protons in the nucleus of an atom, which does not change during a chemical reaction. Chemical reactions involve rearranging electrons and forming new chemical bonds between atoms, but they do not alter the number of protons in the nucleus.
Atomic numbers are determined by the number of protons an atom has. The mass number is determined by the number of protons and neutrons. While the number of protons can't change (as the element itself would change), neutrons can and do vary. These are called isotopes.
The number protons in an atom is called the atomic number (it is this number that tells us which element the atom is). The number of neutrons in an atom can change, but the term for the amount of neutrons is called an isotope. The number of protons and neutrons added together is called the atomic mass.
