Rank the following in terms of increasing electronegativity. 1. Na, N, O, Mg, F 2. Na, Mg, N, O, F 3. F, O, N, Na, Mg 4. F, O, N, Mg, Na 5. F, Mg, Na, O, N

2. Na, Mg, N, O, F (Option 2)

Explanation:

Let's look the electronegativity in the periodic table for each element.

F → 4

Na → 0.9

Mg → 1.2

O → 3.4

N → 3

So the correct orden is Na, Mg, N, O, F

Electronegativity is the ability for the atoms to catch electrons in a bond.

It is a periodic table which increase in a diagonal way, from Fr and Ra, the less electronegatives to F, the most.
