first ionization energy - Ans the energy required to remove the first electron from an atom Why do first ionisation energies increase across a period? - Ans The number of protons increase with the same number of shielding shells Why do melting points decrease down a group? - Ans The ionic/atomic radius increase and there is a smaller charge density. State an equation for the reaction of phosphorus (V) oxide, P4O10 (s), with water. - Ans P4O10 (s) + 6H2O (l) → 4H3PO4 (aq
