In what order should jerome put these models to show the development from the earliest model of the atom to the most recent one

Theories of the atom (from the earliest model of the atom to the most recent one):

1.Dalton's model of the atom - Solid sphere atom

Dalton proposed that matter is composed of small, indivisible objects called atoms.

2.Thompson’s model of atom - Plum pudding model

He discovered electrons.  In this model, the atom is made up of electrons that float in a “cloud” of positive charge.

3.Rutherford's model of the atom - Nuclear model

In this model, atom is  a tiny, dense, positively charged core - nucleus surrounded by lighter, negatively charged electrons.

4.Bohr's model of the atom – Planetary model

Bohr explained that the electrons are around  the nucleus in certain special orbits at different energy levels.

5.Schrodinger model of atom - Quantum model

This theory proposes that electrons move in waves and its location is unknown (there are only “clouds of probability”).
