Statistics published by the National Records of Scotland (NRS) showed that the estimated population of Scotland was 5,347,600 in mid-2014.
The energy needed to remove one or more electrons from a neutral atom to form a positively charged ion is a physical property that influences the chemical behavior of the atom. By definition, the first ionization energy of an element is the energy needed to remove the outermost, or highest energy, electron from a neutral atom in the gas phase. The process by which the first ionization energy of hydrogen is measured would be represented by the following equation.
Rating Newest Oldest. Best Answer: A ground state electron of an element is an outer orbital electron that is in the lowest energy state possible for that electron. An excited state electron has absorbed additional energy and exists at a higher energy level (further from the nucleus) than a ground state electron.
