Chemistry

We know that the periodic dining table arranged fragments depending on how galore(postnominal) negatrons are in its outer(a)mostmost(a) most shell. E.g. Group 1 - has one electron Etc. We know that the metals draw only a a couple of(prenominal) electrons in their outer most shell, and are kind of riant to donate them to the non metals, so as to end up with a entire outer shell. The non metals would need to accept about spare electrons from the metals to fill their outer shell. This means we could divide the metals and the non metals into electron donors and electron acceptors. Valency is the bring up given to the number of electrons that pop off donated or accepted. If they get donated they leave a compulsory valence. E.g. Li= +1 Be= +2 B= +3 If electrons are accepted, we say they work a disallow valency. E.g. F= -1 O= -2 N = -3 Something care coulomb could be a donor or an acceptor, with a valency of 4. ( coarsely accepts) E.g. C= - or + 4 2h20 2 = integral 2 = 2 subscript +1 = 1 superscript The usual thing that happens is that a positive valency chemical nub ( metals ) would donate their electrons to a negative valency chemical (non-metal) E.g.

Li+1 ( lithium)+ F-1 (fluorine)= LiF (Lithium Fluoride) Example. 2Li+1+O-2 = Li2O Be + F = beryllium flouride (BeF2 Be + O = Beryllium Oxide Li + Cl = Lithium Oxide Be + Cl = Beryllium chloride (BeCl2) Na + Cl = particleic number 11 chloride NaCl Na + 0 = 2na+cl = Na2O = 2sodium 1oxygen When a metal tinge donates an electron, it becomes charged. When an Atom gets charged, it results in a valency, and we now call the blood corpuscle an Ion. So any chemicals that alignment together by donating or accepting electrons are really glued together due(p) to positive and negative charges. some(prenominal) new compound place this way is called an Ionic Compound.If you urgency to get a full essay, order it on our website: Ordercustompaper.com
