mass number

number of protons + neutrons combined

ALWAYS a WHOLE number

6

New cards

isotopes

atoms with the SAME number of PROTONS, but DIFFERENT number of NEUTRONS

chemically alike

have different mass numbers

8
New cards

mass number

protons + neutrons

9
New cards

formula

atomic number = protons = electrons
