decreases Ba2+ because add SO42- is increase concentration. reaction with Ba2+
<u>Answer:</u> The number of valence electrons in sulfur atom are 6.
<u>Explanation:</u>
The isotopic representation of sulfur atom is
Valence electrons are defined as the electrons that are present in the outer most orbital of an atom. Electrons present in the orbitals having highest principle quantum number are termed as valence electrons.
Sulfur is the 16th element of the periodic table having 16 electrons.
Electronic configuration of sulfur atom is 
The number of valence electrons present in sulfur atom are 2 + 4 = 6
Hence, the number of valence electrons in sulfur atom are 6.
