Question

explain the position of hydrogen in the periodic table?

Answer 1

Hi friend...


Position of an element in periodic table depends upon its electronic configuration and properties. Hydrogen resembles the elements of group I-A, IV-A and VII-A in some respects. Properties of hydrogen do not completely match any one of the above-mentioned groups. That is why position of hydrogen is still undecided.
In the coming lines we will discuss why hydrogen can not be placed in a particular group in the periodic table.

Hope it help's U..!!

Answer 2

(i) The position of Hydrogen in the periodic table is unique.
(ii) Its properties resemble with both Alkali metals(IA) and halogens(VIIA) because it can loose one electron like alkali metals as well as gain one electron as halogens.
(iii) So,it is placed at the top of both alkali metals and halogens.
