1.	What is ionization energy and its formulae to find it?
Answer» An atom consists of a central nucleus that contains positively charged protons and a number of NEUTRONS specific to the given atom. A number of negatively charged electrons orbit the nucleus at various distances. ... Determine what atom you WANT to USE for calculating the ionization energy. IONIZATION ENERGY FORMULA The energy ESSENTIAL to take away an electron from a gaseous atom A or a gaseous molecule AB is titled as ionization energy. Referring to the following equation. A mass spectrometer can determine the ionization energy. The ionization energy or potential is therefore sometimes also called the “threshold” or “APPEARANCE” energy or potential.
