Which of the bohr diagrams of oxygen and beryllium is more reactive and explain why?

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8

the answer is c.the valence of the atoms combine .

the correct answer would be b) volume versus temperature, because they are also directly proportional.
