Answer:
(1). Similar to alkali metals, hydrogen has 1 electron in its outermost shell and can form compounds with non-metals (such as HCl, etc.). However, it has non-metallic character, is a gas (while alkali metals are solid) and cannot lose its valence electron.
(2). Hydrogen has no neutron, deuterium has one, and tritium has two neutrons. ... The isotopes of hydrogen have, respectively, mass numbers of one, two, and three. Their nuclear symbols are therefore 1H, 2H, and 3H.
(3). (1)General Format: Metal + Dilute Acid → Salt of Metal & Acid + Hydrogen.
(2) With Hydrochloric Acid: Zn + 2HCl → ZnCl2 + H2
(4).. uses of hydrogen are..
welding
rocket fuel
reduction of metallic ores.

Answer:
Like alkali metals, hydrogen has one electron in its valency shell. ...
Valance shell electronic configurations of hydrogen and alkali metal are same. ...
Both hydrogen alkali metals are good reducing agents.
Like alkali metals hydrogen can also form halides.
2)naturally hydrogen has 3 main isotopes known as
- protium (hydrogen-1)
- deuterium (hydrogen-2)
- tritium(hydrogen-3)
3)Hydrogen is produced when granulated zinc is reacted with dilute hydrochloric acid. This is a general procedure for producing hydrogen. Besides, hydrogen can also be prepared by reacting zinc with aqueous alkali.
4)
- hydrogen is an ideal fuel; It is the fuel with highest caloric value, It is used in rockets still it cant be used in vehicles because it is highly reactive and catches fire easily, so it cant be stored safely.
- methanol production, in hydrodealkylation, hydrocracking, and hydrodesulfurization.
- commercial fixation of nitrogen from the air in the Haber ammonia process
