In what order does the electronegativity of elements increase and decrease? And in what order do the metallic properties increase?

Electronegativity is the ability of atoms in elements to take away electrons. In the periodic table of elements, electronegativity in periods increases from left to right, and in groups – from bottom to top. Thus, the most electronegative element is fluorine (F), and non-metallic properties also change.
Metallic properties or electropositiveness – the ability of elements to donate electrons – increase from right to left in periods and from top to bottom in groups. The most active metal is francium (Fr).
