Whats the first ionsation energy

The first ionisation energy is the energy needed to remove one mole of electrons from one mole of atoms in their gaseous state to form one mole of 1+ ions (also in gaseous state)

Explain first ionisation energy in example of magnesium

Take 1 electron from every atom of mg, to form one mole of 1+ ions also in their gaseous state

The energy needed to do this is called the first ionisation energy.

What is the second ionisation energy

The second ionisation energy is the energy needed to remove one mole of electrons from one mole of 1+ ions in their gaseous state to form one mole of 2+ ions (also in gaseous state)

What is successive ionisation energys

When we can continue removing electrons and measuring the ionisation energy each time.

How to work out the ionisation energy shown from an equation

The ionisation energy shown is the same as the charge on the ion produced. For example, third ionisation energy produces an ion with 3+ charge.
