How many unpaired electrons are present in each of the following ground-state atoms?.

The ground state of an electron, the energy level it normally occupies, is the state of lowest energy for that electron.The ground state of an electron, the energy level that an electron normally occupies, is the lowest energy state of that electron. There is also the maximum energy an electron can have and remain part of that atom.This does not represent the physical position of the electron within the atom. It represents the average energy of an electron at a given level. An atom is said to be in the ground state when all electrons are in the lowest possible state. TheGround state configuration is the most stable and lowest energy configuration. An excited state configuration is a higher energy configuration. Valence electrons are the electrons used for bonding.Learn more about ground state here:- https://brainly.com/question/1621498#SPJ4
