ATOMIC NUMBER

H

slide16
THE ATOMIC NUMBER IS EQUAL TO THE NUMBER OF PROTONS AN ATOM HAS.THE NUMBER OF PROTONS IS WHAT DETERMINES WHAT ELEMENT IT IS

HYDROGEN

MASS NUMBER

H

the mass number equals the number of protons plus the number of neutrons so of neutrons mass atomic
THE MASS NUMBER EQUALS THE NUMBER OF PROTONS PLUS THE NUMBER OF NEUTRONSSO# OF NEUTRONS =MASS # - ATOMIC #
atoms do not have an overall charge so the number of electrons
ATOMS DO NOT HAVE AN OVERALL CHARGE SO THE NUMBER OF ELECTRONS…

IS THE SAME AS THE NUMBER OF PROTONS (OR THE ATOMIC #)
