Bonding Basics

Front

Valence electrons

Back

The negatively charged subatomic particles that are responsible for bonding elements together

Front

Covalent bond

Back

A chemical bond formed when electrons are shared

Front

Ionic bond

Back

A chemical bond formed when electrons are transferred.

Front

Isoelectronic

Back

Having the same number of electrons or the same electron configuration

Front

Electronegativity

Back

A measure of an atom’s ability to attract an electron in a chemical bond

Front

Polar bond

Back

A covalent bond in which one of the elements pulls the electrons more strongly and gains a partial negative charge

Front

Non-polar bond

Back

A covalent bond in which the electrons are shared evenly (or nearly evenly)

Front

Back

Substance made of 2 different elements

Front
