Question

Indicate whether each statement is true or false regarding covalent bonds.

1. Covalent bonds are formed when two or more atoms share protons.
2. A nonpolar covalent bond means that electrons are shared equally between two atoms.
3. A polar covalent bond means that one nucleus is attracting the electrons more than the other.
4. A double covalent bond is the result of two atoms sharing two electrons.
5. A single covalent bond means that two atoms are sharing a pair of electrons.

Answer 1

Covalent bonds are formed when electrons are shared between atoms. Nonpolar covalent bonds have equal sharing of electrons, while polar covalent bonds have unequal sharing. The statements provided are evaluated as either true or false.

Step-by-step explanation:

Covalent bonds form when electrons are shared between atoms and are attracted by the nuclei of both atoms. In pure covalent bonds, the electrons are shared equally. In polar covalent bonds, the electrons are shared unequally, as one atom exerts a stronger force of attraction on the electrons than the other. The ability of an atom to attract a pair of electrons in a chemical bond is called its electronegativity.

A nonpolar covalent bond is one in which the electrons are shared equally between two atoms. A polar covalent bond is one in which one atom has a greater attraction for the electrons than the other atom. If this relative attraction is great enough, then the bond is an ionic bond.

Based on the statements:

1. False. Covalent bonds are formed when two or more atoms share electrons, not protons.
2. True. A nonpolar covalent bond means that electrons are shared equally between two atoms.
3. True. A polar covalent bond means that one nucleus is attracting the electrons more than the other.
4. True. A double covalent bond is the result of two atoms sharing two electrons.
5. True. A single covalent bond means that two atoms are sharing a pair of electrons.
