The atomic number is the number of protons and electrons in the element.
Beryllium Atomic number: 4 Atomic Mass: 9.012
By N, I assume you mean Nitrogen. Nitrogen's Atomic number is 7, and its atomic mass is ~14.011.
A bigger atomic number means a larger amount of electrons and protons

if you mean atomic number then the answer is cadmium.
atomic number is 37
Beryllium Atomic number: 4 Atomic Mass: 9.012
The meaning of the atomic number is: number of protons and electrons (for californium is 98).
The atomic number is the number of protons in the nucleus of the atom.
Atomic number = Number of protons = Number of electrons (in the neutral state) Also the atomic number is number of a chemical element in the periodic table of Mendeleev.
Sodium is a non metal element. Atomic number of it is 11.
By N, I assume you mean Nitrogen. Nitrogen's Atomic number is 7, and its atomic mass is ~14.011.
If you mean to ask what element has an atomic number of 13, then the answer is aluminum (Al).
A bigger atomic number means a larger amount of electrons and protons
NH3 is a compound, not an element. It does not have an atomic number. If you mean the number of atoms in the molecule the answer is 4: 1 nitrogen and 3 hydrogen. This is not the same as atomic number.

The atomic number is equal to either the number of electrons or the protons of a particular atom. The atomic mass in a.m.u. is equal to the sum of protons and neutrons in an atom.
