Frequently Asked Questions about Ionisation Energy
What is ionisation energy?
Ionisation energy is the energy required to remove one mole of electrons from one mole of gaseous atoms under standard conditions.
What is the first ionisation energy of an element?
The first ionisation energy is the energy required to remove one mole of the outermost electrons from one mole of gaseous atoms under standard conditions.
Why is the second ionisation energy greater than the first?
The second ionisation energy is greater than the first because an electron is removed from a positive ion, which requires more energy.
What is the second ionisation energy?
The second ionisation energy is the energy required to remove one mole of the next outermost electrons from one mole of gaseous cations that have a charge of +1.
