Determine if the sequence below is arithmetic or geometric and determine the common difference/ratio in simplest form. 64,16,4,…

This is a (geometric/arithmetic) sequence and the (common ratio/common difference) is equal to .

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.

step-by-step explanation: it is d

i dont know what you want me to answer for this but im guessing 2: 11?
