Put in order from smallest to largest radii: 1. AI, Na, CI, Ar, Mg
2. S, Te, Po, Se, O
3. Cl, Ca, S, P, Ga, Mg
4. F, CI, Br, I, At

1. Ar, Cl, Al, Mg, Na

2. O, S, Se, Te, Po

Explanation:

Just remember the trends. From left to right, atomic radius decreases because proton increases and pulls electrons closer. From top to bottom, atomic radius increases because there are more electron shells.

shield volcanos are angry and get mad over the smallest things so much that there heads erupt   pahoehoe and a'a lava. a composite volcano is the poller opposite of a shield volcano. its   peaceful thing and knows how to control its emotions.
