Which of the following statements is true?
1. Electronegativity is a measure of the ten-
dency of an atom to lose electrons.
2. As electron a±nity increases (becomes
increasingly negative), electronegativity de-
creases.
3. When ionization energy increases, elec-
tronegativity increases.
4. Ionic radii are always larger than atomic radii for the same element.
5. Electron a±nity is a measure of the
amount of energy needed to remove an elec-
tron from an atom.

Use electron-dot notation to demonstrate
the formation of an ionic compound involving
the elements Na and S.
