Video transcript

Hello everyone today. We are being asked to find how many valence electrons there are in a tin atom based on the periodic table. We know that tin has an atomic number or atomic symbol of S. N. And it isn't column for a. The column represents the number of valence electrons that an element will have, And therefore we can say that 10 had a total of four valence electrons. I hope this helped, and until next time.

The molecule shown here is styrene, C8H8, a benzene derivative that is used to make a number of polymers, including polystyrene. The shorthand notation for the benzene ring (described in Section 8.6) is used. Three of the carbon–carbon bonds are numbered in the structure.

a. Which of the three bonds is the strongest?

b. Which of the three bonds is the longest?

c. Which of the three bonds is best described as halfway between a single and a double bond? [Sections 8.6 and 8.8]

Consider the Lewis structure for the polyatomic oxyanion shown here, where X is an element from the third period (Na - Ar). By changing the overall charge, n, from 1- to 2- to 3- we get three different polyatomic ions. For each of these ions (b) determine the formal charge of the central atom, X;
