Four atoms are arbitrarily labeled D, E, F, and G. Their electronegativities are as follows: D 5 3.8, E 5 3.3, F 5 2.8, and G 5 1.3. If the atoms of these elements form the molecules DE, DG, EG, and DF, how would you arrange these molecules in order of increasing covalent bond character?

Friday, January 15, 2016 Exact Numbers Significant Figures (Sig Figs) do NOT count when dealing with exact numbers. No uncertainty; infinitely significant Counting numbers are exact Section 2.3: Significant figures in Calculations Rule to follow: The term with the least amount of Sig.
