Answer:
Compounds
Explanation:
Chemical reactions involving more than one element mostly give rise to compounds when transfer of electrons occurs.
The compounds are as a result of the combination of the individual elements and radicals.
Isotopes occur naturally while alpha (α) and beta (β) particles are as a result of nuclear reactions.
Answer: compounds
Explanation:
A physical reaction is defined as the reaction in which a change in shape, size takes place. No new substance gets formed in these reactions.
A chemical reaction is defined as the reaction in which a change in chemical composition takes place. A new substance or compound is formed in these reactions.

Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass. It can be decomposed into simpler constituents using chemical reactions. Example: water [tex]H_2O[/tex]
Isotopes, alpha and beta particles are formed in nuclear reactions.
