Question

What is the significance of atomic models?

Answer 1

Atomic Model:

• Atomic models were crucial in describing how compounds made up of two or more atoms formed.
• It's worth noting that atomic models were also needed to explain atoms' emission of electromagnetic radiation, as well as the origin/source of the radiation and its characteristics.

Dalton’s atomic theory:

• According to Dalton's atomic theory, the atom is the ultimate indivisible particle that makes up all matter.
• This notion was contradicted by the discovery of subatomic particles like Protons, Neutrons, and Electrons.
• This necessitated the development of an atomic model capable of accounting for and explaining the stability of all atoms and molecules, as well as comparing the variations in the physical and chemical properties of various elements.
