Covalent Bonding

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond formed when two atoms share one or more pairs of electrons.

Front

What types of elements typically form covalent bonds?

Back

Covalent bonds typically form between nonmetals.

Front

What is a molecule?

Back

A molecule is a group of two or more atoms bonded together by covalent bonds.

Front

What is the difference between polar and nonpolar covalent bonds?

Back

Polar covalent bonds occur when electrons are shared unequally, while nonpolar covalent bonds occur when electrons are shared equally.

Front

What is an example of a polar molecule?

Back

Water (H2O) is an example of a polar molecule due to its bent shape and unequal sharing of electrons.

Front

What is an example of a nonpolar molecule?

Back

Oxygen gas (O2) is an example of a nonpolar molecule because the two oxygen atoms share electrons equally.

Front

What are the physical properties of covalent compounds?

Back

Covalent compounds typically have lower melting and boiling points compared to ionic compounds and may exist as gases, liquids, or low-melting solids.

Front

Why are covalent compounds poor conductors of electricity?

Back

Covalent compounds do not have free-moving charged particles, which makes them poor conductors of electricity.

Front

What is a diatomic molecule?

Back

A diatomic molecule is a molecule composed of two atoms, which can be of the same or different elements, such as O2 or HCl.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to form bonds in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.
