Electronic cereal: • Start with diatomic molecules • 2 atoms of the same element (7) • Rules to follow: Make every compound • Use different colors for each atom • Show how each atom contributes electrons to the bond and the lone pairs • Determine shape & polarity • Polarity is?
Lewis structures show bonds & predict shape (VSEPR) Ionic – Transfer of valence electrons Covalent – Sharing of 2 valence electrons F₂ H₂0 NH₃ CH₄ O₂ N₂ • Kand F • Be and O • Mg and Br
Opposites Attract • Find ions that can bond • Write the symbol and the charge • Write the new compound formed by combining the ions. • Name the compound. • Write at least 15 compounds. • Ten should include subscripts.
Names & Formula Booklet • Student created! • Where formulas did not copy properly: • Page 1 Ionic Bonds • AlBr₃; Li₂S; KCl, BaO, CaS, Li₃N, MgI₂, Na₃P • Page 5 Covalent bonds • I₃N; S₂O, CBr₄, SiO₂
