Explain why magnesium oxide has a higher melting point than sodium chloride.Mg²⁺ and O²⁻ ions have a higher charge than sodium and chloride therefore the electrostatic forces between the ions are much stronger. This requires more energy to break.Mg²⁺ and O²⁻ ions are larger than sodium and chloride therefore the electrostatic forces between the ions are much stronger. This requires more energy to break.Magnesium and oxygen are more reactive elementsSodium chloride is a simple molecular substance so there are only weak intermolecular forces which require little energy to breakQuestion 1 of 22 Loading... 2.

When are ions attracted to each other?When the ions are very smallWhen the ions are the same sizeWhen the ions have the same chargeWhen the ions are oppositely chargedQuestion 14 of 22 Loading... 15. Explain, in terms of the arrangement of electrons in its atoms, why neon is very unreactiveNeon has 8 electrons in the outer shell, so it is full. Therefore it does not easily gain or lose electronsNeon has the same number of electrons and protons so it is unreactiveNeon has an even number of electrons so it doesn\'t need to form bondsNeon is a noble gasQuestion 15 of 22 Loading... 16. Why do elements in the same group of the periodic table have similar chemical properties?Elements in the same group of the periodic table have the same number of electrons in their outer shellElements in the same group of the periodic table are all the same type of element (metal, non-metal etc.)Elements in the same group of the periodic table have the same number of protonsElements in the same group of the periodic table have different numbers of electrons in their outer shellQuestion 16 of 22 Loading... 17.
