Someone pls help me find the perimeter of this shape !! i’ll mark brainliest

240 :)

Step-by-step explanation:

easy all u have to do is just add all the sides together but the empty sides with no number u have to try to figure out how much meters that is.

they're both 36 because they're the same size as the meters on the other side.

so its going to be

60+36+36+36+36+36

hope this helps

good luck!

answer: plz give a pic and answer choices so i can answer!

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.
