Explanation:

Question 7

Electronegativity increases across a period (from left to right) and decreases down a group. Na and Mg are in period 3 (Na is group 1, Mg is group 2), N, O, F are in period 2 (N - group 15, O - group 16, F - group 17). So, Na < Mg < N < O < F.

Electronegativity is crucial in determining the type of chemical bond (ionic, polar covalent, non - polar covalent). It helps in understanding how electrons are shared or transferred between atoms.

Answer:

Na, Mg, N, O, F
