Am i the only one who thinks its hilarious to see these people with like hot random people for their pfp -who are NOT them- and then they go and ask you these really simple like 6-7th grade questions when there supposed to be like 18 nobody okok

lol this is free points btw if u havent already noticed

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.
