Solution

To predict the order of increasing electronegativity for the elements Rb, K, and Na, we need to compare their electronegativity values. Electronegativity is a measure of an atom's ability to attract electrons towards itself in a chemical bond.

  1. Rb (Rubidium): The electronegativity of Rubidium is approximately 0.82.

  2. K (Potassium): The electronegativity of Potassium is approximately 0.82 as well.

  3. Na (Sodium): The electronegativity of Sodium is approximately 0.93.

Comparing the electronegativity values, we can see that the order of increasing electronegativity for these elements is:

Rb < K < Na

Therefore, the correct order from smallest to largest electronegativity is Rb, K, Na.
