The total number of valence electrons in a molecule of sof2 is ________.
tamaranim1 [39]
Answer:
            There are 26 valence electrons in SOF₂.

Explanation:
                   Valence electrons are calculated by adding the valence electrons present in valence shell of each element present in SOF₂. So,

# of Valence e⁻s in S  =  6

# of Valence e⁻s in O  =  6

# of Valence e⁻s in F  =  7

# of Valence e⁻s in F  =  7

Now, add all valence electrons,

                                =  6 + 6 + 7 + 7

                                =  26 Valence Electrons
