Question

Discuss position of hydrogen in mordern periodic table of elements

Answer 1

Hydrogen is placed at the first in the Morden periodic table due to its atomic number 1. It occupies a unique position in the periodic table. In its properties, it behaves like alkali metals as well as halogens. In the periodic table, it is placed at the top of the alkali metals. Hydrogen can lose its only electron to form a hydrogen ion (H+) in which case it resembles alkali metals (M) that yield M+ ions.
