noble gases
metalloids
nonmetals
halogens
2
Which group is represented in this image?
noble gases
nonmetals
metalloids
halogens
3
Why does radius decrease from left to right on the periodic table?
Fewer electron shells make smaller atoms
Decreased electron-electron repulsions
It doesn't; radius increases from left to right
More protons mean increased force on the valence electrons
