Every element has a different number of protons and electrons in each atom, and this amount is what the atomic number tells you.
The atomic number is equal to the number of protons in the atomic nucleus. It is an individual characteristic.
It is the number of protons in the nucleus of an atom. It defines what element the atom is.
For every element, the atomic number, symbol of the element and atomic mass is listed. And on most periodic tables, the state of matter. If you know how, you can distinguish how many protons, neutrons and electrons an element has. The atomic number (number on top of the letter) is the number of protons, and also the number of electrons. If you subtract the atomic mass (the number on the bottom of the symbol) from the atomic number, you can find out how many neutrons are in that element. Also, the atomic mass is a representation of how much a mole of that element weighs in grams. For example, a mole of calcium weighs 40.078 grams.
The atomic number is unchanged.
The atomic number is the number of protons in an atom of an element.
Protons distinguish one lement from another because the number of protons in an element is equal to the atomic number, and each element has its own atomic number for example Hydrogen's atomic number is 1, which means it has 1 proton
The unique number of protons in the nucleus of an atom is an element's atomic number. This identifies an element.

The number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table
Elements are distinguished by their atomic number, which is the number of protons in the nucleus of an atom. The element's atomic number determines its chemical properties.
Actually atomic number is the number of protons or number of electron's a neutral atom ,both are equaling the atom loses the electron it becomes charged. For example's case of hydrogen the atomic number is in case of helium the number is 2.helium is inert because is shell is completely filled. Same with the case of all inert gasses in case of atomic instability the atom radiates the ray sand other particle's a result ,the atomic number varies and hence the atom turns to be the atom of other element. I hope this will be convincing.

The atomic number or z number or the number of protons is what makes one atom different from another. The atomic number or z number or the number of protons is what makes one atom different from another.
An element's atomic number, or number of protons, differentiates one element from another.
