Question

Which of the following best describes the differences between atoms of solid sodium and atoms of liquid sodium?

• A. Atoms of solid sodium have smaller atomic radii than atoms of liquid sodium.
• B. Atoms of solid are more chemically reactive than atoms of liquid sodium
• C. Atoms of liquid sodium move around more freely than atoms of solid sodium.
• D. Atoms of liquid sodium experience stronger attractive forces than atoms of solid sodium.

Answer 1

The correct option is C Atoms of liquid sodium move around more freely than atoms of solid sodium.

Atoms of liquid sodium move around more freely than atoms of solid sodium.
This is because, atoms of liquid sodium experience weaker attractive forces than atoms of solid sodium. Hence, the option (C) is answer.
