Front

What is the correct Lewis formula for molecular oxygen (O2)?

Back

Structure B.

Front

Which of the following represents an ionic bond?

Back

Calcium chloride (CaCl2).

Front

What are valence electrons?

Back

Electrons in the outermost shell of an atom that are involved in forming bonds.

Front

How do you determine the total number of valence electrons in a molecule?

Back

Add the valence electrons of all atoms in the molecule.

Front

What is a covalent bond?

Back

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

Front

What is the octet rule?

Back

Atoms tend to form bonds until they are surrounded by eight valence electrons.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.
