Question

Which is an example of a covalent bond?
A.Chlorine accepts an electron from calcium to form a stable bond.
B.Ions in a bar of pure iron are surrounded by a large number of valence electrons.
C.There are less than 16 valence electrons in 2 chlorine atoms, but they form a stable bond.

Answer 1

A is not the answer

Answer 2

A covalent bond is a chemical bond that involves sharing a pair of electrons between atoms in a molecule.

Answer 3

Anything with ions involved is an ionic or metallic bonding and is not covalent.

Answer 4

C should be the answer

Answer 5

A is ionic bond, B is metallic bond, and C is covalent bond

Answer 6

Exactly, another helpful tool is to remember that covalent bonds only occur between non-metals while ionic bonds occur between a metal and a nonmetal, and metallic bonds only occur between two metals (usually)
