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.
