Covalent bonds and compounds

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

Which elements typically form covalent bonds?

Back

Nonmetals typically form covalent bonds with other nonmetals.

Front

What is the difference between polar and non-polar covalent bonds?

Back

Polar covalent bonds occur when electrons are shared unequally between atoms, while non-polar covalent bonds occur when electrons are shared equally.

Front

What is electronegativity?

Back

Electronegativity is a measure of an atom's ability to attract and hold onto electrons.

Front

How do covalent compounds differ from ionic compounds?

Back

Covalent compounds are formed by the sharing of electrons, while ionic compounds are formed by the transfer of electrons.

Front

What is the significance of the VSEPR theory?

Back

The VSEPR theory (Valence Shell Electron Pair Repulsion) is used to predict the 3D shape of molecules based on the repulsion between electron pairs.

Front

What are intermolecular forces?

Back

Intermolecular forces are forces of attraction or repulsion between neighboring molecules.

Front

Why do covalent compounds generally have low melting and boiling points?

Back

Covalent compounds have low melting and boiling points due to weak intermolecular forces.

Front

What is a molecular formula?

Back

A molecular formula shows the number and type of atoms in a molecule, e.g., H2O for water.

Front

What is a single covalent bond?

Back

A single covalent bond is formed when two atoms share one pair of electrons.
