Where would you expect to find zinc and calcium on the periodic table?

Zinc and Calcium form compound by losing electrons which
are in their outermost shell. By doing so, they form positive ions. Both of them have 2
electrons in their outermost levels.

Calcium should be
found in group 2 and Zinc in the group 10 of the periodic table. This has been predicted
using the number of electrons in the last two shells of Ca which is 8, 2 resp. and is
18, 2, respectively for Zn.

Elements with 2 electrons in
the outermost shell and 8 electrons in the shell before that should have properties
similar to Ca. Similarly elements with 18 electrons in the shell before the outermost
and 2 electrons in the outermost shell should have the properties of
Zn.
