A variable is a symbol for a number that we don't yet know. It is usually a letter such as x or y.
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."
Such a number is often called a "constant".
if a number can change randomly it is called a variable
The only way to change the number of protons in an atom is with a nuclear reaction.
chemical reactions are involved by the participation of electrons only.During chemical reaction number of protans remains as it is. No change in number of protans.Number of protans is also called atomic number.So no change in number of protans means no change in atomic number. That's why atomic number is not change during a chemical reaction.
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.
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
The common ratio.
It is called periodic law.
The mass number will change. Mass number - Atomic number = Number of neutrons. So, if the number of neutrons change the mass number will change. The atomic number would not change because the atomic number is equal to the number of protons and if the number of protons change, then the element would change.
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.
(change in speed) divided by (time required to make the change)This number is the magnitude of average acceleration.
