Document Summary

Session outline: session sign in ~5 min, warm up/activities ~75 min, cool down: review homework questions ~10 min. Warm up: reviewing polarity (class discussion: covalent bonding occurs when two atoms share electrons due to a mutual transfer of electrons from one atom to another. A polar bond is a type of covalent bond between two or more dissimilar atoms, in which electrons are shared unequally. Therefore, that side of the bond will have a slightly negative charge, and the other side will have a slightly positive charge. The greater the electronegativity difference, the more ionic the bond is. Bonds that are partly ionic are called polar covalent bonds. Nonpolar bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal: can a bond between two of the same atoms be polar, give an example of a polar covalent bond.
