CHE-Ch 8 Vocab (Covalent Bonds)

Front

What is a covalent bond?

Back

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

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 electrical charge.

Front

What is a Lewis structure?

Back

A Lewis structure is a diagram that uses dots to represent valence electrons and shows how they are arranged in a molecule.

Front

What does VSEPR stand for?

Back

VSEPR stands for Valence Shell Electron Pair Repulsion, a model used to predict the shape of molecules.

Front

What is the difference between a polar covalent bond and a nonpolar covalent bond?

Back

In a polar covalent bond, electrons are shared unequally, while in a nonpolar covalent bond, electrons are shared equally.

Front

What is the significance of valence electrons in covalent bonding?

Back

Valence electrons are the outermost electrons of an atom and are involved in forming covalent bonds.

Front

What is a molecule?

Back

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

Front

What is resonance in chemistry?

Back

Resonance refers to the way some molecules can be represented by two or more valid Lewis structures.

Front

What is a sigma bond?

Back

A sigma bond is the strongest type of covalent bond formed by the direct overlap of atomic orbitals.

Front

What is a pi bond?

Back

A pi bond is a type of covalent bond that is formed when the lobes of two p-orbitals overlap.
