Are they isotopes?
No.They have different no. of protons so they are different elements]]> 2018-06-28 04:21:05 UTC https://padlet.com/777nicholaskam/1k1Group4/wish/268817434 https://padlet.com/777nicholaskam/1k1Group4/wish/268922702 The group number at the top of the periodic table is how many electrons there are on the outer shell
Eg
What is special about group 7?
The elements in group 7 has 7 electrons on the outer shell.
