hope this is helpful God Bless you stay safe!

try getting the n by it's self and by doing that you would draw a line in the middle of the equal side all the way down(doesn't matter how far you go) then you subtract 1 to both sides so positive minus 1 doesn't go so you cross it out then you subtract 3 by 1 and get 2 once you have that you should have 2-2n=2n

Step-by-step explanation:

did you get the answer yet?

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.
