Rank the following elements in order of decreasing atomic radius.
br, f, cl, i
rank from largest to smallest radius. to rank items as equivalent, overlap them.

I > Br > Cl > F

Explanation:

Bromide (Br), Fluorine (F), Chlorine (Cl) and Iodine (I) are halogens and they are in the same group of the periodic table. We know that as we go down in the group the atomic radius will increase. The decreasing order of the atomic radius will be:

I > Br > Cl > F

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.
