Question

How many valence electrons in an electrically neutral Sulfur atom

Answer 1

Sulfur atom have atomic number 16 thus,

neutral sulfur atom have total 16 electron and it's electronic configuration is

1s²2s²2p⁶3s²3p⁴

first two shell are comletly filled by 2 and 8 electron respectively.and

third shell contain 2 s and 4 p electron it is not comletly filled so it is valence shell.

Thus, there is 6 valence electrons in an electrically neutral Sulfur atom.
