The number of protons and electrons and hence the identity of the element too.

The Atomic number
This is a problem of atomic physics !
The atomic number.
The atomic number generally. the atomic number is the number of protons(or electrons) an atom has.
carbon
The carbon atom, which has six protons and six neutrons, is arbitraily declared to have an atomic weight of 12.
Atomic Number identifies the following:No. of protons (same as the atomic number)No. of electrons (mostly same as no. of protons)Approximate Atomic Mass (No. of neutrons are roughly equal to or near to no. of protons)
To identify neutrons, we need to subtract the atomic number and atomic mass..Since neutrons are the negative ones, the electrons are the positive ones. So clearly, ....shut up !!!!!!!!!ha di ka kasabot diha?/?/???
The number of protons and electrons and hence the identity of the element too.
it is unique for each element and distinguishes one element from another based on the number of protons in the nucleus. Just like how a fingerprint can identify a specific individual, the atomic number can identify a specific element in the periodic table.
Yes, if a periodic table that includes atomic numbers, as most periodic tables do, is available for reference
