Answer 1

Answer:

Electromagnetism is a branch of Physics, that deals with the electromagnetic force that occurs between electrically charged particles

Answer 2

Answer:

Reactant: a substance that takes par in and undergoes change during a reaction.

Mass number: alternative titles: atomic mass number, nucleon number. mass number , in nuclear physics the sum of the numbers of protons and neutrons present in the nucleus of an atom.

Chemical bonding: a chemical bond is a lasting attraction between atoms , ions or molecules that enables the formation of chemical compounds.

Inert elements: an inert chemical substance is one that is not generally reactive . this is a synonym for "inactive" with respect to chemical reaction
