Elements tend to react to achieve electron configurations similar to those of

gases.

Multiple Select

Which of the following statements about noble gases is/are correct?

• They have completely filled outermost energy levels.

• They have eight valence electrons, except helium which has two.

• They are highly reactive.

A chlorine atom has one electron fewer than an

atom.

Multiple Choice

What happens to a sodium atom when it loses one electron?

• It becomes a positively charged ion.

• It becomes a negatively charged ion.

• It remains neutral.

• It becomes a chlorine atom.

Multiple Choice

What is the result of the electron transfer between sodium and chlorine atoms?

• Both atoms achieve a more stable electron arrangement.

• Both atoms become neutral.

Multiple Select

Which of the following statements about atomic and ionic radii are correct?

• Atomic radius is the distance from the center of the atom to its outer edge.

• Ionic radius can be larger or smaller than atomic radius depending on the ion.

• Atomic radii are measured in millimeters.

• There are one billion picometers in a millimeter.
