What is the valency of aluminum?? |
|
Answer» ????? To the point answer is +3 The\xa0valency\xa0of\xa0aluminium\xa0is 3 instead of 5 because the energy required to remove 3 electrons from the outermost shell is less than the energy required to add 5 electrons.\xa0Because\xa0aluminum\xa0has\xa0three, that means\xa0three\xa0fluorines can bond. The make the formula AlF3, also known as\xa0aluminum\xa0trifluoride. Each of the fluorine atoms gets an\xa0electron\xa0to fill their shell, and the\xa0aluminum\xa0loses\xa0three, giving it a filled shell too (remember,\xa0aluminum\xa0has\xa0three\xa0extra\xa0electrons). |
