Question

Write about the position of hydrogen in the periodic table and how you will justify it

Answer 1

Answer:

Hydrogen is the first element of the periodic table & often called protium. Due to the presence of only one electron in its 1s shell, hydrogen exhibits a dual behaviour, i.e., it resembles both alkali metals and halogens. As a result it is placed at the top of the alkali metals in group 1 & also along the halogens in group 17 since just like halogens,it also requires any one electron to have the configuration of the nearest noble gas element.
