The energy required to convert one mole of gaseous atoms into gaseous ions with a single positive charge.
1 of 5
What is the equation for the first ionisation energy?
X(g) --> X (g) + e
2 of 5
Are ionisation energies exothermic or endothermic?
Endothermic. The removal of an electron requires energy to be added in order to overcome the attraction between the electron and positively charged protons in the nucleus.
3 of 5
Define second ionisation energy.
The energy required to convert one mole of gaseous ions with a single positive charge into gaseous ions with a double positive charge.
