110

184-74=110

500

WHY are noble gases the least reactive? (Think Bohr models)

They have a full valence shell, they do not want to share, lose, or gain electrons. 

500

Which element would have a bigger atomic radius, 

K or He and WHY??

K because it would have 4 electron shells instead of 1- It also would have a higher atomic number meaning more protons which in turn means more electrons in the shells. 


Atomic radius goes down as you more left to right and gets bigger as you go down the group.
