Front

What is the correct Lewis dot structure for ammonia (NH₃)?

Back

The Lewis dot structure for ammonia shows nitrogen in the center with three hydrogen atoms bonded to it, and a lone pair of electrons on nitrogen.

Front

What type of ion do metals form?

Back

Cations.

Front

What type of ion do nonmetals form?

Back

Anions.

Front

Is this a correct dot diagram for oxygen (O)?

Back

No, the correct dot diagram for oxygen should have 6 valence electrons represented.

Front

What type of ion results from the gain of electrons?

Back

Anion.

Front

What is a Lewis dot structure?

Back

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

Front

What is the octet rule?

Back

The principle that atoms tend to bond in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.

Front

What is a cation?

Back

A positively charged ion that is formed when an atom loses one or more electrons.
