The energy required to remove an electron from an atom
Chat with our AI personalities
The first ionization energy represents the amount of energy required to remove the outermost electron from a neutral atom in the gaseous phase. It reflects the atom's ability to lose an electron and form a cation. A higher first ionization energy indicates a stronger attraction between the electron and the nucleus.
The first ionization energy of mercury is 10.44 eV, while the second ionization energy is 18.76 eV. These values represent the energy required to remove one or two electrons, respectively, from a gaseous mercury atom to form a positively charged ion.

The first ionization energy is 1681 kJ/mol.
ionization potential energy. but remember the atom must be neutral .
Across a row on the periodic table ionization energy increases. Down a column, ionization energy decreases. --------------------------------------------------------- The first Ionization energy of Boron is 800.6 kJ mol-1
