The number of bonds an atom can form without violating the octet rule is reflected in the number of holes the "ball" for that atom has in the ball-and-stick model set. Based on that information, how many holes would you expect to see in models of atoms for each of the following elements: (4 points total; 1 point per element) a. Carbon (C)

four holes

Explanation:

A ball and stick model is a representation of a molecule that can show the number of bonds and sometimes, the stereochemistry of the molecule under study.

The number of holes on present in the ball and stick model for any atom corresponds to the number of bonds that particular atom can form without violating the octet rule.

Carbon is usually tetravalent, it forms four bonds to other atoms. Hence we expect carbon to have four holes.

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).
