Question

why is hydrogen refered as noble gas​

Answer 1

PLEASE PLEASE MARK AS BRAINLIST AND LIKE IT ❣️❣️❣️

Explanation:

DUE TO THE FOLLOWING REASON.....

Both hydrogen and halogens require one electron to complete their octets. Hence, hydrogen can gain one electron to form a uninegative ion.

Also, it is less reactive than halogens. Owing to these reasons, hydrogen cannot be placed with alkali metals (group I) or with halogens (group VII).

Answer 2

Answer:

When hydrogen atoms pair up to form diatomic molecules H2 each atom of hydrogen achieves an electron structure where the first shell is full, a full outer shell is sometimes referred to as similar to a noble gas electron structure. But hydrogen gas is not a noble gas.
