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.
Electrons have the lowest energy when closest to the nucleus. Under resting conditions, the electrons are in the lowest possible energy level called. ground state. When atom absorbs a quantum of energy, it causes the electron to jump to a higher energy level called the excited state. Excited atom is energetically unstable, so electron will fall back down very rapidly and energy will given off in the same amount as absorbed but now in the form of a photon of light.
