Question
How many valence electrons does Aluminum Have?
- 1 Valence electron
- 2 Valence electron
- 3 Valence electron
- 4 Valence electron
Hint:
3 Valence electron
The correct answer is: 3 Valence electron
Aluminum has 3 valence electrons. Aluminum has 13 electrons in total. In the first shell 2 electrons are orbiting, in the second shell 8 electrons are orbiting. In the third and last shell, 3 electrons are there, hence, 3 valence electrons.
