Covalent Bonding and Nomenclature

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 determines the shape of a molecule?

Back

The shape of a molecule is determined by the electron pairs around the central atom, lone pairs of electrons around the central atom, and the number of attached 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 a molecule with two bonded atoms and no lone pairs?

Back

Linear.

Front

What is the molecular shape of a molecule with three bonded atoms and no lone pairs?

Back

Trigonal planar.

Front

What is the molecular shape of a molecule with four bonded atoms and no lone pairs?

Back

Tetrahedral.

Front

What is the chemical formula for Dinitrogen Monoxide?

Back

N₂O.

Front

What type of elements typically form covalent bonds?

Back

Nonmetals + Nonmetals.

Front

What is a Lewis structure?

Back

A Lewis structure is a diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that may exist.

How many bonds are around the central atom in a molecule with two single bonds?

Back

2 bonds.
