Question

Electropositivity trend in periodic table​

Answer 1

Answer:

Periodic Trends in the Electropositivity of Elements

Since electronegativity increases across a period, electropositivity decreases across periods. Similarly, since electronegativity decreases down a group, electropositivity increases while traversing down a group.

Answer 2

Answer:

The reactivity of the metals increases from the top to the bottom in a group because the tendency of an element to lose the electrons increases in a period. In a periodic table, the electropositivity or the metallic characters increases from the top to the bottom of the group.
