Question

hydrogen is metal or non metal because according to periodic table it is non metal...
Then why hydrogen is also available in reactivity series of metals...
And series shows that hydrogen have lots of properties that's similar to metal so tell me hydrogen is metal or non metal..
If you want to discuss about hydrogen just dm me on instagram... Id available in my bio​

Answer 1

Answer:

Hydrogen is a nonmetal and is placed above group in the periodic table because it has ns1 electron configuration like the alkali metals. However, it varies greatly from the alkali metals as it forms cations (H+) more reluctantly than the other alkali metals.

Answer 2

Answer:

Explanation;

hydrogen helps to compare the reactivities of metals.

the metal placed above hydrogen in the series can displace from acids such as HCI.since they are more reactive
