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
Answer
Explanation:
Step1: Recall carbon's atomic number
Carbon has atomic number 6. Its electron - configuration is 1s²2s²2p². The number of valence electrons is 4 (from the 2s and 2p orbitals in the outermost shell).
Step2: Analyze each diagram
We need to find the diagram with 4 dots representing valence electrons.
- Diagram A has 4 dots.
- Diagram B has 3 dots.
- Diagram C has 1 dot.
- Diagram D has 8 dots.
Answer:
A.
