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.

atomic mass is the no. of protons+no. of nuetron
The atomic number tells you how many protons and electrons are in a specific element.Atomic number tells us about protons. Number of protons that atom contains.
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.

An element's atomic number tells us the number of protons in an atom of that element. It is used to uniquely identify the element and determine its placement on the periodic table. The atomic number also corresponds to the number of electrons in a neutral atom of that element.
The number of protons in the nucleus of an atom determines the atomic number. The atomic number corresponds to the number of protons in an atom's nucleus and identifies the element.
it tells us that the number is equal to the number of protons plus the number of nuetrons in the nucleus of an atom
Atomic models tell us about the structure of an atom which is based on what we know about how atoms behave. But it is not necessary that it will be a genuine picture of the structure of an atom.
