Which pair of radicals is a pair of like radicals?
(see image) !

I just finished taking this test and I just wanted to confirm for all you humans out there, that FencingParry4 is correct! (yay! wooo! celebra-ate!) the answer is indeed 7√3  and  9√3 Great job fencing!

Step-by-step explanation:

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
