Question

how does the electropositive nature of the elements as we go to the top of reactivity series

Answer 1

the more reactive metals are placed at the top and the least at the bottom.

Answer 2

The actual reactivity series are:

Electropositivity series:

Li (Lithium)

K (Potassium)

Ba (Barium)

Sr (Strontium)

Ca (Calcium)

Na (Sodium)

Mg (Magnesium)

Al (Aluminium)

Mn (Manganese)

(C) (Carbon)

Zn (Zinc)

Cr (Chromium)

Co (Cobalt)

Ni (Nickel)

Sn (Tin)

Pb (Lead)

(H) (Hydrogen)

Cu (Copper)

Hg (Mercury)

Ag (Silver)

Pt (Platinum)

Au (Gold)

Electronegativity series:

F (Fluorine)

O (Oxygen)

Cl (Chlorine)

N (Nitrogen)

Br (Bromine)

I (Iodine)

S (Sulphur)

C (Carbon)

H (Hydrogen)

P (Phosphorus)

As we move from bottom to top in electropositivity series, the electropositive character of the elements increases and electronegativity decreases, and vice-versa for electronegativity series of non-metals.
