Question

what is meant by the atomic number (z) of an element​

Answer 1

Answer:

The symbol for atomic number, Z, stands for "Zahl", which means number in German. ... Once there was evidence that this was also the charge of the atom, Z came to be called "Atomzahl", or atomic number.

Explanation:

The atomic number or proton number (symbol Z) of a chemical element is the number of protons found in the nucleus of every atom of that element. ... It is identical to the charge number of the nucleus. In an uncharged atom, the atomic number is also equal to the number of electrons.
