Explain the plum pudding model of the atom and how it was developed.

The plum pudding model of the atom was developed following the discovery of electrons. It proposed that the atom is a cloud of positive charge with negative electrons embedded in it, without considering the existence of protons and neutrons.

What were the key components of John Dalton's model of the atom?

John Dalton's model considered the atom as a solid sphere that could not be divided into smaller parts. It did not include protons, neutrons, or electrons.

Differentiate between elements and compounds based on their atomic composition.

Elements consist of one type of atom, with each atom having the same number of protons. Compounds are made of different types of atoms chemically bonded together.

Describe the discoveries of sub-atomic charged particles that contributed to the development of the atomic model.
