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.
The ionization energy of an atom is equal to the amount of energy given off when an electron is added to an atom. When an electron is added to an atom, we call the energy given off the electron affinity (EA). So, IE=EA. For most atoms, the initial electron affinity is exothermic meaning energy is given off.
