Question

carbon has _________ valence electrons.
options: 0, 4, 1, 6 (with a periodic table image)

Explanation:

Step1: Identify Carbon's Group

Carbon (C) is in Group 14 (or IVA) of the periodic table.

Step2: Relate Group to Valence Electrons

For main - group elements, the number of valence electrons is equal to the group number (for Groups 1 - 2 and 13 - 18). Group 14 elements have 4 valence electrons. So carbon, being in Group 14, has 4 valence electrons.

Answer:

4 (corresponding to the option with 4, likely the second option: "4")
