The common ratio of the sequence -5, -20, -80, ... is 4.

-5 * 4 = -20; -20 * 4 = -80

-5 * 4 = -20; -20 * 4 = -80

(b2)3 **Weegy:** Bond order of 1.
If you draw the MO diagram, the pi(u) molecular obitals are the only filled molecular orbtials for n=2 l=1, (each are half filled, 2 electrons in total). [ So bond order is 1-0 = 1.
I have no idea if that makes any sense without drawing out the MO. ] **User:** Write 6,000,370 in scientific notation.
