Back

It becomes positively charged.

Front

What do covalent compounds do?

Back

Share electrons between non-metals.

Front

What do atoms that form positive ions tend to do?

Back

Tend to lose electrons.

Front

What happens when an atom gains an electron?

Back

It becomes negatively charged.

Front

What is helpful to know when determining if two atoms will bond?

Back

Valence electrons, whether the elements are metals or nonmetals, and the electronegativity of the atoms.

Front

What are valence electrons?

Back

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

Front

What is an ion?

Back

An atom or molecule that has a net electrical charge due to the loss or gain of one or more electrons.

Front

What is the difference between ionic and covalent bonding?

Back

Ionic bonding involves the transfer of electrons, while covalent bonding involves the sharing of electrons.

Front

What is electronegativity?

Back

A measure of the tendency of an atom to attract a bonding pair of electrons.

Front

What is a positive ion called?

Back
