X(g) --> X+(g) + e- 3 of 6 What is the equation for 3rd ionisation energy of sodium? Na2+(g) --> Na3+(g) + e- 4 of 6 Define: Second Ionisation Energy The energy per mole to remove an electron from gaseous atoms with a single positive charge. 5 of 6 When the molecules in a sample are bombarded with electrons...what happens? An electron is removed from the molecule to form a molecular ion M+(g) 6 of 6
