What is a valence shell?

• The innermost energy level of an atom.

• The energy level that contains only protons.

• The outermost energy level of an atom that contains electrons.

• The total number of electrons in an atom.

What is the primary reason atoms form chemical bonds?

• To increase their atomic mass.

• To achieve a full valence shell.

• To become electrically neutral.

• To decrease their number of protons.

In the formation of sodium chloride (NaCl), what happens to the valence electron of the sodium atom?

• It is shared with another sodium atom.

• It is gained by the chlorine atom.

• It remains in the sodium atom's outermost shell.

• It is lost to the environment.

When a sodium atom loses its single valence electron, what is the state of its new outermost electron shell?

• It becomes completely empty.

• It becomes partially filled with 7 electrons.

• It becomes completely full with 8 electrons.

• It remains unchanged.
