The state is the lowest possible energy level that an electron can occupy. When the electron gains energy, it may move to a higher energy level. This is called the state.

the answer is minerals.

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
