How many protons are in the nucleus of an atom of chlorine?

Answer 1

Well, this one is easy...there are 17 protons....

The identity of a nucleus is defined by the number of MASSIVE, positively-charged nuclear particles contained in its nucleus, and here #Z_"the atomic number"=17#...the which number unequivocally identifies a CHLORINE nucleus. But how do I know this? Do I have access to some table that lists the name of each element according to #Z#? You're damned right I do...
