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.

the ratio of the conjugate base to the acid required to attain the desired ph.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
