Question

List the three subatomic particles of the atom. Indicate the charge of each. What is the difference between an atom and a molecule? What is the difference between a molecule and a compound? Provide an example of an atom, a molecule, and a compound.

Answer 1

Three subatomic particles are electron, proton and nuetron.

Charge on electron = -1. 6*10^-19 C

Charge on proton =+1.6*10^-19

Charge on nuetron = 0

Atom is A smallest unit that cannot exist freely and that shows all the properties of the element. Example - H, He

Molecule = is formed when two or more atoms combine example - H2

Compund - is formed when different types of atoms combine

Example - CO2
