WebSep 16, 2024 · Ionization energy (IE) is the amount of energy required to remove an electron from an atom in the gas phase: A ( g) → A + ( g) + e − Δ H ≡ I E. IE is usually expressed in kJ/mol of atoms. It is always positive because the removal of an electron always requires that energy be put in (i.e., it is endothermic). WebDensity (g cm−3) Density is the mass of a substance that would fill 1 cm3at room temperature. Relative atomic mass The mass of an atom relative to that of carbon-12.
