Explanation:

When highly reactive non-metals react with highly reactive metals, the compounds formed are generally ionic in nature. This means that they are made up of positively charged metal ions and negatively charged non-metal ions.

1. Formation of Ionic Compounds:
When a highly reactive non-metal reacts with a highly reactive metal, the non-metal tends to gain electrons and become negatively charged, while the metal tends to lose electrons and become positively charged. This transfer of electrons results in the formation of ions, and these oppositely charged ions are held together by strong electrostatic forces, forming an ionic compound.

2. High Reactivity of Non-Metals and Metals:
Highly reactive non-metals have a strong tendency to gain electrons because their outermost energy level is almost empty, and they can achieve a stable electron configuration by gaining electrons. On the other hand, highly reactive metals have a strong tendency to lose electrons because their outermost energy level is almost full, and they can achieve a stable electron configuration by losing electrons.

3. Ionic Bonding:
The high reactivity of non-metals and metals makes it easier for them to undergo electron transfer, resulting in the formation of ions. The attraction between these oppositely charged ions forms an ionic bond. The ionization energy of metals is generally lower than that of non-metals, which facilitates the loss of electrons by metals. The electronegativity of non-metals is generally higher than that of metals, which promotes the gain of electrons by non-metals. These factors contribute to the formation of ionic compounds.

4. Covalent Bonding:
Covalent bonding occurs when non-metals react with non-metals, where they share electrons to achieve a stable electron configuration. In the case of highly reactive non-metals and highly reactive metals, the difference in reactivity and electron configuration leads to the formation of ionic compounds rather than covalent compounds. The high electronegativity difference and the strong tendency for electron transfer make the formation of covalent bonds less favorable in these combinations.

Therefore, the compounds formed by highly reactive non-metals with highly reactive metals are generally ionic in nature.
