Question

Unlike ionic bonds, covalent bonds involve the

A. gain of one or more electrons by one atom from another.
B. development of positively and negatively charged ions.
C. sharing of electrons between atoms.
D. loss of one or more electrons from one atom to another.

Answer 1

sharing of electrons between atoms

Answer 2

The correct answer is C. sharing of electrons between atoms. Covalent bonds function by having for example an oxygen atom that needs two electrons to reach stability, and hydrogen needs one electron to reach it, so two hydrogens give their one to oxygen and oxygen gives it's two to hydrogen, one each, and they share it and make H2O, water.
