The number of protons in the nucleus of an atom signifies which element it is. this is very important number which is known as proton number or atomic number and is given by the symbol z. for eg. hydrogen has 1 proton and its atomic number is 1, helium has 2 protons and its atomic number is 2, carbon has 6 protons and its atomic number is 6, sodium has 11 protons and its atomic number is 11.

Yes, Atomic number is one of the important numbers
The atomic number is decided with the help of the number of protons and electrons it has.
The protons are equal to the numbers of electrons.
As per Rutherford the atom is neutral so it's net charge is zero
So, protons are equal to electrons
Now, both electrons and protons and atomic number is denoted by z.
Also, this atomic number is unique. Each element has its own atomic number which is never the same of any two elements.
Now,
Number of neutrons are calculated by the formula : atomic mass - z , where z is the number of atoms i. E. Atomic number.
Now, electronic configuration of atoms are done as per the bohr-bury scheme which we will talk later as it is not in concern now.
