VSEPR & Molecule Shapes

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 atoms typically form covalent bonds?

Back

Covalent bonds are typically formed between two nonmetals or metalloids.

Front

How many electrons are shared in a single bond?

Back

In a single bond, 2 electrons are shared.

Front

How many electrons are shared in a double bond?

Back

In a double bond, 4 electrons are shared.

Front

What is a triple bond?

Back

A triple bond is a type of covalent bond where three pairs of electrons (6 electrons) are shared between two atoms.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of bond where electrons are shared unequally between two atoms, resulting in a molecule with a slight charge.

Front

What is a nonpolar covalent bond?

Back

A nonpolar covalent bond is a type of bond where electrons are shared equally between two atoms.

Front

What is the VSEPR theory?

Back

VSEPR (Valence Shell Electron Pair Repulsion) theory is a model used to predict the geometry of individual molecules based on the repulsion between electron pairs.

Front

What is the molecular shape of CO2?

Back

The molecular shape of CO2 (carbon dioxide) is linear.

Front

What is the molecular shape of NH3?

Back

The molecular shape of NH3 (ammonia) is trigonal pyramidal.
