Question

the dots in each diagram represent valence electrons orbiting the nucleus of an atom. which diagram shows the valence - electron pattern for a carbon atom?
o a
o b
o c
o d

Explanation:

Step1: Recall carbon's valence electrons

Carbon has 4 valence electrons.

Step2: Examine each diagram

Check which diagram has 4 dots representing valence - electrons.

Answer:

(Assuming the diagram with 4 dots is one of the options, without seeing the actual dot - counts in each diagram we can't precisely pick the letter, but the correct answer is the diagram with 4 dots representing valence electrons)
