QQ: Write & name the formula of the ionic compound created when a chromium (II) cation bonds with Bromine.Write the formula for gold(I) sulfide.In the ionic compound Co3N2, which cation is present? Co (II) or Co (III)Slide2
Ionic Bonds Containing Transition MetalsSlide3
Friday Funnies!!!Slide4
Today’s Object: I understand how covalent bonding is different from ionic bonding.Slide5
Binary Moleculeconsist of exactly two nonmetals Examples include HF, NO2, and P2O5Slide6
Back to the idea of “chemical soup”Slide7
7 Valence electrons 7 Valence electrons Both want 1 moreSlide8Slide9
Instead of transferring electrons, some atoms share electrons.Covalent BondsSlide10

Nonpolar Bond: Electrons are shared equallySlide11

Have No Fear Of Ice Cold Bears!Hydrogen Nitrogen Fluorine Oxygen Iodine Chlorine Bromine H N F O I Cl BrSlide16
Polar Bonds: Caused by the unequal sharing of the electrons of a covalent bondRemember…Polar Bonds are always covalent because they are sharing …not taking.Slide17
The atom with the greatest attraction for the electrons has a partial negative charge.Slide18Slide19
Polar or Nonpolar?????Slide20Slide21Slide22
Naming Covalent Compounds1. First: start with lower group #(In same group, start with lower one)2. First element is just its name.3. The second one: add -ideUse Greek prefixes to indicate how many of each atom. Don’t put “mono” on the first atomSlide23
