Questions relating to Chemical bonding
1.Why atoms form bonds?
2.What is chemical Bonding?
THE A'LEVEL VIEW OF IONIC BONDING Electrons are transferred from one atom to another resulting in the formation of positive and negative ions. The electrostatic attractions between the positive and negative ions hold the compound together. So what's new? At heart - nothing. What needs modifying is the view that there is something magic about noble gas structures. There are far more ions which don't have noble gas structures than there are which do. Some common ions which don't have noble gas structures You may have come across some of the following ions in a basic course like GCSE. They are all perfectly stable , but not one of them has a noble gas structure. Fe 3+ [Ar]3d 5 Cu 2+ [Ar]3d 9 Zn 2+ [Ar]3d 10 Ag + [Kr]4d 10 Pb 2+ [Xe]4f 14 5d 10 6s 2 Noble gases (apart from helium ) have an outer electronic structure ns 2 np 6 .
