Homework Help: Science-Periodic Table

Posted by Sara on Thursday, April 8, 2010 at 8:18pm.

whats the connection/relationship between the # of protons in the nucleus of an atom & and atomic # of the element?

The atomic number tells you the number of protons in the nucleus of the atom.
The atomic number is the number of protons in the nucleus of an atom. The number of protons in an atom's nucleus determines the chemical identity of that atom. It tells us which element it is.

Please add any other information and correct me if I'm wrong, thanks.
