Covalent hydrides are formed when hydrogen reacts with the p-block nonmetals by sharing its electrons. ... Relative to hydrogen's reaction with other elements, hydrogen can readily react with nitrogen, oxygen, and halogens because they are very electronegative, therefore reactive.......and sorry.

Non-Metals and Covalent Hydrides

Covalent hydrides are compounds formed between non-metals and hydrogen, whereby the non-metal atoms share electrons with the hydrogen atom to form covalent bonds. Non-metals react with hydrogen to form covalent hydrides and this process can be explained as follows:

1. Non-Metallic Elements

Non-metals are a group of chemical elements that do not have the properties of metals. They are generally poor conductors of heat and electricity, have low melting and boiling points, and are brittle in their solid state. Examples of non-metals include hydrogen, carbon, nitrogen, oxygen, and fluorine.

2. Covalent Bonding

Covalent bonding is a type of chemical bonding in which atoms share electrons to form a bond. This type of bonding is typically found in non-metals and occurs when two atoms have similar electronegativities.

3. Formation of Covalent Hydrides

When non-metals react with hydrogen, they share electrons to form covalent hydrides. The non-metal atoms bond to the hydrogen atom by sharing electrons, and the resulting compound is held together by covalent bonds.

4. Properties of Covalent Hydrides

Covalent hydrides have a number of properties that are different from ionic compounds, which are formed between metals and non-metals. Some of the properties of covalent hydrides include:

- Low melting and boiling points
- Poor electrical conductivity
- Insolubility in water
- Brittle in their solid state

5. Examples of Covalent Hydrides

Some examples of covalent hydrides include:

- Methane (CH4)
- Ammonia (NH3)
- Water (H2O)
- Hydrogen fluoride (HF)

Conclusion

In conclusion, non-metals react with hydrogen to form covalent hydrides. This process involves the sharing of electrons between the non-metal atoms and the hydrogen atom. Covalent hydrides have properties that are different from ionic compounds and some examples include methane, ammonia, water, and hydrogen fluoride.
