If a calcium atom can give off two electrons in a reaction with nitrogen, which of the following formulas represent the
compound formed?
a CaN2
b Can
c Ca3N2
d None of the above

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.

the answer is a for sure mark brainliest i had got this right on usatestprep

the answer your looking for is c).

the correct answer is c
