Which is the electronic configuration of the outermost shell of group 16 elements?

In the modern periodic table, the elements are arranged in the increasing order of their atomic number. This arrangement is based on the modern periodic law, which states that the properties of elements are a periodic function of their atomic numbers. In the modern periodic table, each column is called a group and each row is called a period. Elements within the same group show similarity and gradation in properties. This is due to the same number of electroms in the outermost shell . Based on the above paragraph, answer the following question: What is the number of valence electrons in an element of group 1 and group 18 respectively?

Assertion (A)Although Zn is the member of Ist series yet not a transition element. Reason ( R) The orbitals in Zn are completely filled in ground as well as in oxidation state.

Two elements X and Y belong to groups 1 and 2 respectively in the same period. Compare them with respect to (a) the number of electrons in the outermost shell, (b) the number of valence electrons , (c) metallic character, (d) size of the atoms and ( e) formulae of the oxdies , hydrides and chlorides.
