Formation of Ionic Compounds Next we examine the reaction of IIA metals with VIIA nonmetals. This reaction forms mostly ionic compounds. Notable exceptions are BeCl 2 , BeBr 2 , and BeI 2 which are covalent compounds. One example is the reaction of Be and F 2 . Be (s) + F 2(g) BeF 2(g) Formation of Ionic Compounds The valence electrons in these two elements are reacting in this fashion. 2s 2p 2s 2p Be [He] ¯ ® Be 2+ [He] F [He] ¯ ¯ ¯ ® F - [He] ¯ ¯ ¯ ¯ Next, draw the Lewis dot formula representation of this reaction.

Unformatted text preview: You do it! Formation of Ionic Compounds The remainder of the IIA metals and VIIA nonmetals react similarly. Symbolically this can be represented as: M (s) + X 2 ® M 2+ X 2-M can be any of the metals Be to Ba. X can be any of the nonmetals F to Cl. Formation of Ionic Compounds For the reaction of IA metals with VIA nonmetals, a good example is the reaction of lithium with oxygen. The reaction equation is:...
