Most Upvoted Answer
How do metal and non metal react with hydrogen. Explain with examples?
¶¶ Only some metals like sodium, potassium, calcium, magnesium react with hydrogen to give a metal hydride which is ionic in nature. For eg.
2Na + H2 >>> 2NaH
¶¶ Non-metals react with hydrogen to form covalent hydrides. For example: Sulphur combines with hydrogen to form hydrogen sulphide.
2Na + H2 >>> 2NaH
¶¶ Non-metals react with hydrogen to form covalent hydrides. For example: Sulphur combines with hydrogen to form hydrogen sulphide.

How do metal and non metal react with hydrogen. Explain with examples?
Reaction of Metals and Non-Metals with Hydrogen
Metallic and non-metallic elements can react differently with hydrogen. Here are some examples:
Metallic Elements:
- Sodium: When sodium reacts with hydrogen gas, it forms sodium hydride (NaH) according to the following equation: 2Na(s) + H2(g) → 2NaH(s). This reaction is highly exothermic.
- Iron: Iron reacts with hydrogen gas to form iron hydride (FeH2) according to the equation: 3Fe(s) + 4H2(g) → Fe3H2(s). This reaction is reversible and occurs at high temperatures.
Non-Metallic Elements:
- Oxygen: Oxygen, a non-metal, does not react with hydrogen under normal conditions. However, under certain circumstances, such as in the presence of a catalyst, oxygen can react with hydrogen to form water.
- Carbon: Carbon, another non-metal, can react with hydrogen to form various hydrocarbons. For example, the reaction between carbon and hydrogen can produce methane (CH4) according to the equation: C(s) + 2H2(g) → CH4(g).
In conclusion, while metallic elements like sodium and iron readily react with hydrogen to form metal hydrides, non-metallic elements like oxygen and carbon can also undergo reactions with hydrogen under specific conditions to form different compounds. Each reaction has its own set of conditions and products, showcasing the diverse reactivity of elements with hydrogen.
