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.

Calcium is a metal element. Atomic number of it is 20.
The atomic number tells us the number of protons in the nucleus of an atom. It determines the element's identity and its place on the periodic table. Elements with different atomic numbers have different chemical properties.
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.
the # of protons
The periodic table tells us:The elements atomic massThe elements atomic numberIf the element is a gas, metal, etc.How many protons, electrons and neutrons an element hasThe name of the elementWhich elements could have similar properties (nearby in the chart)(Oops that was already six things (but some of them depend on the others)
For elements it's the atomic number not the "Period Number." This number tells you how many protons a single atom of that element has in its nucleus. The "period number" is a dimensionless quantity used in fluid dynamics.
The periodic table is in order of atomic mass
it tells us that the number is equal to the number of protons plus the number of nuetrons in the nucleus of an atom
The nitrogen has 7 protons. your welcome!
