QUIZ 1. What is the number of valence electrons around the carbon atom? a. One b. Two c. Three d. Four Answer: d. There are four valence electrons around the carbon atom. Rather than taking on electrons entirely, which would make for a crowded state of repulsing electrons, the carbon atom will share these four valence electrons with another atom so that there can be a balance between the shared electron and the positively-charged atom it shares the electrons with. 2. What is the number of valence electrons around the hydrogen atom? a. One b. Two c. Three d. Four Answer: a. Hydrogen has a single electron with only one available for bonding; this means that it has one valence electron in total. 3. Sending an electron to a higher orbital from a lower orbital in order to have an electron able to bind with another atom is called what? a. Elevation b. Hybridization c. Promotion d. Energization Answer: c. Promotion involves sending an electron to a higher orbital from a lower orbital in order to have a free electron available to bind with another atom.
