It cannot be an atom of oxygen.

Front

What will an atom of neon MOST likely do to be stable?

Back

Neither gain nor lose any valence electrons.

Front

What is an ionic bond?

Back

A bond formed when one atom transfers electrons to another atom.

Front

What is a valence electron?

Back

Electrons in the outermost shell of an atom that are involved in chemical bonding.

Front

What is an isotope?

Back

Atoms of the same element with different numbers of neutrons.

Front

What is the difference between atomic mass and atomic number?

Back

Atomic mass is the total number of protons and neutrons, while atomic number is the number of protons.

Front

What is a molecule?

Back

A group of atoms bonded together, representing the smallest fundamental unit of a chemical compound.
