Which type of bond involves one atom losing 1 or more electrons and
another atom gaining 1 or more electrons? *
ionic bonds
O
polar covalent bonds
nonpolar covalent bonds
both kinds of covalent bonds

Ionic bonds

Explanation:

Ionic bonds occur when 1 atom looses 1 or more electrons while its recipient recieves 1 or more of its electrons.

Polar and nonpolar covalent bonds are where  unequal sharing of electrons occur with polarity.

Thus, it wouldn't be polar covalent bonds, nonpolar covalent bonds, or both kinds of covalent bonds. It would be ionic bonds.

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.
