A LEVEL CHEMISTRY WITH VERIFIED QUESTIONS AND ANSWERS Weak acid - an acid that is only slightly ionised/dissociated in aqueous solution Oxidation - loss of electrons Reduction - gain of electrons Ionic bonding - The electrostatic attraction between oppositely charged ions Covalent bonds - sharing of a pair of electrons Electronegativity - the ability of an atom to attract the electrons in a covalent bond Relative atomic mass - The weighted mean mass of an atom of an element ...

Give the full electron configuration of an Al atom and a Cr3+ ion : 1s2 2s2 2p6 3s2 3p1 1s 2s2 2p6 3s2 3p6 3d6 Deduce the formula of the ion that has a charge 2+ with the same electron : Sr2+ Deduce the formula of the compound that contains 2+ ions and 3- ions that both have the same electron configuration as argon : CaP Deduce which of Na+ and Mg2+ is the smaller ion 2 marks : Mg 2+ Both have the same number of shielding however Mg2+ has more protons so higher nuclear charge and so...
