Haha! Thanks for try so hard to show me.. thanks again... If the different in the electronegativity between the ions in a compound is small, the polarisation is big or small? Polarisation cause the partially covalent properties of an ionic compound is it? If yes for both questions above, then how come the different in electronegativity between Ag ion and Cl ion is small, but there is partially covalent properties between them?
oops.. sorry, is melting point. "lower atomic radius of Al"? then how about magnesium. sorry a... my english is not pro. my chemistry also not pro. so can u all explain in the way that is more easy for me to understand?
why the boiling point of aluminium is more than magnesium by 10C only?
