Question

Covalent compounds occur __________.

A. when nonmetals share electrons

B. when nonmetals gain or lose electrons

C. only between metals

D. between a metal and a nonmetal that share electrons

Answer 1

Covalent compounds occur __________.

A. when nonmetals share electrons

Covalent bonds can be found in diamond (carbon), Quartz (SiO2) etc

Answer 2

Answer: Covalent compounds occur when non-metals share electrons.

Step-by-step explanation:

Covalent compound is defined as the compound which is formed by the sharing of electrons between the atoms forming a compound.

These are usually formed when two non-metals react.

For Example:
`CH_4\text{ and }NH_3` are covalent compound formed by the combination of non-metals only.

Ionic bond is defined as the bond which is formed by complete transfer of electrons from one atom to another atom. This bond is usually formed between a metal and a non-metal.

For Example: NaCl is formed by the combination of sodium and chlorine atoms.

Hence, covalent compounds occur when non-metals share electrons.
