How does electropositivity of elements very as we move -
1.down the group
2.across a period
3.which atomic property increase in both the cases whether we move across a period or down a group.

1) increases
2) decreases
3) atomic number
*up to down for a group
left to right for a period

manavukani:
yeah its atomic no.
no mass might be less in some cases like in Mendeleev's table
there is an increase in nuclear charge
are u in class x
i am in 12
nuclear charge increases but some cases like
Tellurium & Iodine
Atomic no. & mass of tellurium are 52 & 127.6
while that of iodine are 53 & 126.9
you can check

) Electropositive character increases down a group due to decrease in the effective nuclear charge.
(ii) Electropositive character decreases across a period due to increase in the effective nuclear charge.
(b) Atomic number/Atomic mass.
