A single covalent bond involves two atoms sharing one pair of electrons.

True

False

True

Explanation: Covalent bonds occur when electrons are shared between two atoms. A single covalent bond is when only one pair of electrons is shared between atoms.

Answer: The given statement is true.

Explanation:

When there is sharing of an electron between two atoms then the bond formed between them is covalent bond.

For example, atomic number of calcium is 20 and its electronic configuration is 2, 8, 8, 2. Whereas atomic number of fluorine is 9 and its electronic configuration is 2, 7. So, in order to attain stability calcium will donate its extra electron to fluorine atom and thus readily combines with two fluorine atoms.

Thus, we can conclude that the statement a single covalent bond involves two atoms sharing one pair of electrons, is true.
