4. Methane, CH4, is one carbon atom bonded to four hydrogen atoms. In order to show
how carbon and hydrogen bond, the electron dot configurations must beknown for each
element. Which statement describes the electron dot configuration for carbon when it
bonds with four hydrogen atoms?
a. The carbon symbol C with two dots on the left and right sides
b. The carbon symbol C with two dots on the top and two dots on the bottom
c. The carbon symbol C with one dot on each the top, bottom, left, and right sides
d. The carbon symbol C with two dots on the top, two dots on the bottom, and one
dot on each side.
