Question

Sulfur has fewer valence electrons than chlorine. True or False

Answer 1

The answer is true I believe bc I just took that test.

Answer 2

Answer:

True

Explanation:

Valence electron:

No. of electrons present in the outermost shell of any atom is called valence electrons. Valence electrons determines the chemical properties of element.

Atomic no. of S = 16

Electronic configuration of S = $1s^22s^22p^63s^23p^4$

Energy shell (n = 3) is the outermost shell

Valence electrons = 6

Atomic no. of Cl = 17

Electronic configuration of S = $1s^22s^22p^63s^23p^5$

Energy shell (n = 3) is the outermost shell

Valence electrons = 7

So, sulfur has 6 valence electrons and Cl has 7 valence electrons.

The statement 'Sulfur has fewer valence electrons than chlorine.' is true.
