Explanation:

The electronegativity of an atom is used most times to determine how reactive or non-reactive an atom will be.

  • Electronegativity is as measure of the relative tendency with which the atoms of the element will attract valence electrons in a chemical bond.
  • Across a period electronegativity increases from left to right and decreases down a group.
  • We use electronegativity to determine the reactivity of most non-metals. The higher the electronegativity of non-metals the more reactive they are. This is why fluorine is the most reactive non-metal because it has the highest electronegativity.

For metals, the more electropositive they are, the more reactive they become. Electropositivity is a measure of the tendency of atoms of an element to lose electrons. The larger the size of a metal, the more reactive it is and more electropositive.

The most reactive metal is francium and it occurs at the lower left corner.
