Multiple Select

Which of the following statements about valence electrons are correct?

They are found in the outermost shell of an atom.

They determine the chemical bonding properties of an atom.

They are always equal to the atomic number.

They can participate in the formation of chemical bonds.

Multiple Choice

Which of the following statements best explains why argon does not readily form chemical bonds with other elements?

Argon has a full set of valence electrons, making it stable.

Argon has only one valence electron, making it reactive.

Argon has no electrons in its outermost shell.

Argon can easily lose electrons to form bonds.
