Final answer:
In the list provided, from least to greatest electronegativity, it is Rubidium (Rb), Sodium (Na), Aluminum (Al), Nitrogen (N), and Fluorine (F) with Fluorine having the highest electronegativity value.The order from least to greatest electronegativity is as follows: Rb < Na < Al < N < F.
Step-by-step explanation:
Electronegativity is a measure of an atom's ability to attract and hold onto electrons when it is part of a compound.
According to Linus Pauling, one of the most famous chemists of the twentieth century, the electronegativity values vary predictably across the periodic table. Fluorine has the highest electronegativity value, while the elements down and to the left of the periodic table have lower electronegativities.
Regarding the elements in question, aluminum (Al), sodium (Na), nitrogen (N), fluorine (F), and rubidium (Rb), the order from least to greatest electronegativity is as follows: Rb < Na < Al < N < F. Rubidium, being an alkali metal, has a very low electronegativity, while fluorine, a halogen, has the highest electronegativity of all elements.
