The observed pattern is electronegativity increases from left to right within a row of the periodic table.

In the periodic table, the most active metals are arranged on the far right while the most active non metals are arranged on the far left of the periodic table.

  • The most active metals are found in group 1, which decreases as you move to group 3 and this similar to decrease in electropositivity.
  • As, the electropositivity  decreases, the electronegativity increases and the most active non metals are found in group 7 of the periodic table.
  • The most electronegative element is Fluorine which is found in group 7 of the periodic table.

Thus, we can conclude that electronegativity increases from left to right within a row of the periodic table.
