The atomic number of sulfur is 16. Sulfur combines with hydrogen by covalent bonding to form a compound, hydrogen sulfide. Based on the number of valence electrons in a sulfur atom, predict the molecular formula of the compound.a. HSb. HS2c. H2Sd. H4S

When two atoms share a pair of electrons, the bonding is referred to as:

a) Ionic.

b) Covalent.     

c) Unstable.          

d) Hydrogen.     

e) Polar.

What makes a covalent bond nonpolar?

a) The bonded atoms share electrons unequally.

b) The bonded atoms share electrons equally.

c) The bonded atoms have equal electronegativities.

d) The bonded atoms have unequal electronegativities.

e) a and d only.

f) b and c only.
