A chemical change is a change in which the type and the number of atoms that make up a substance are changed and rearranged.
In chemical changes<span>, the molecules or atoms in the reactants interact to form new substances. On the other hand, in a </span>physical change<span>, like a state </span>change<span> or dissolving, no new substance is formed.</span>
Explanation : A chemical change is usually when a compound or molecule undergoes a change which is normally irreversible and it generates a new product than it was before.
So, when we consider the process of making up of substances from atoms it makes the substance as an irreversible product.
Also a new product which is formed is the substance which is not at all similar to atoms.
Answer: Another useful feature of the periodic table is that most tables provide all the information you need to balance chemical reactions at a glance. The table tells each element's atomic number and usually its atomic weight. The typical charge of an element is indicated by its group.
