Electrical Engineering XYZ MCQs
Silicon has:
- Two valence electrons
- Four valence electrons
- Eight valence electrons
- None of the above
Correct answer: 2. Four valence electrons
Explanation: Silicon has four valence electrons. This is because silicon belongs to group 14 of the periodic table, also known as the carbon group. Elements in this group have four valence electrons in their outermost shell. Valence electrons are the electrons in the outermost shell of an atom, and they are crucial in determining an element’s chemical properties and bonding behavior.
So, the correct answer to the multiple-choice question would be: “Four valence electrons.”
