Question

Silicon Has How Many Valence Electrons

Answer 1

Answer:

It has two electrons in its first shell, eight electrons in the second shell, and four electrons in the third shell. Since the electrons in the third shell are the outermost electrons, silicon has four valence electrons

Electronic configuration: [Ne] 3s

Hence, the correct answer is 3

Answer 2

Answer:

There are total 14 electrons in a silicon atom and fout (4) valence electrons

Explanation:

Silicon has total 14 electrons

As 2 electrons in most inner orbit

8 in 2nd

4 in valence orbit
