Front

What is an ionic bond?

Back

A bond formed when one atom transfers electrons to another, resulting in charged ions.

Front

What is a covalent bond?

Back

A bond formed when two atoms share one or more pairs of electrons.

Front

What are metallic bonds?

Back

Bonds formed between metal atoms where electrons are shared in a 'sea' of electrons.

Front

How do you determine the charge of an ion formed by losing electrons?

Back

The charge is positive and equal to the number of electrons lost.

Front

What is the octet rule?

Back

Atoms tend to bond in a way that gives them eight valence electrons.
