Answer:
False
Explanation:
It is not correct to assert that a chemical change has occurred if the number of atoms is greater after the reaction than it was before the reaction.
For every chemical reaction, the law of conservation of mass must be strictly adhered.
The law states that "during a chemical reaction, matter is neither created nor destroyed, atoms are simply rearranged".
By the virtue of this law, the number of atoms at the beginning and the end of the reaction must remain the same for this law to be applicable.

Answer: A pair of elements will most likely form an ionic bond if one is a metal and one is a nonmetal. These types of ionic compounds are composed of monatomic cations and anions.
Explanation:
A pair of elements will most likely form an ionic bond if one is a metal and one is a nonmetal. These types of ionic compounds are composed of monatomic cations and anions.
Explanation:
The chart below shows monatomic ions formed when an atom loses or gains one or more electrons, and the ionic compounds they form. You can check your periodic table to see that the cations are monatomic ions formed from metals, and the anions are monatomic ions formed from nonmetals.
