Question

The modern model of the atom describes electrons in a little less specific detail than earlier models did. Why is it that being less sure about the placement of electrons in an atom is actually an improvement over earlier models?

Answer 1

The modern model of atom is unable to show the speed of atoms which make it less sure about its improved version.

Explanation:

The atomic model has under-went a drastic change in the past few decades. The first model was developed by Demoncritus in 450 B.C. which was accurate about the existence of atom as matter particles but he was inaccurate about the divisibility of matters.

Many other scientists have developed various models of atom over time, they are- John Dalton(1800), J.J. Thompson(1897), Ernest Rutherford( 1899), Neils Bohr. Neils Borh talked about the nucleus in his model and about the electrons orbiting the nucleus. However, this modern model lacked the observation of the speed of electrons.
