Atomic number = Number of protons
The atomic number represents the number of protons. The atomic mass represents the number of protons + neutrons.
The atomic mass number tells us the total number of protons and neutrons in an atom's nucleus. It is used to determine the mass of an atom and is necessary for calculating the atomic weight of an element.
Atomic number, being a characteristic property (property that is diff. for each element), it identifies the element, For instance, Oxygen has an atomic number of 8, and it's the only one that has that atomic number, same with any other element, except that no other element has an atomic # of 8. No two elements can share an atomic number.

Calcium is a metal element. Atomic number of it is 20.
the # of protons
The atomic number is the number of protons in the nucleus.The Atomic Number of an element helps us to locate that particuarler element on the Periodic Table of Elements.

it tells us that the number is equal to the number of protons plus the number of nuetrons in the nucleus of an atom
