The nuclear atom differs from the uniform sphere model, because they both are made from different atoms because of the elements.
Dalton's mental image of an atom can be best represented by a solid, indivisible sphere with no internal structure, similar to a billiard ball. This model suggested that atoms were the smallest, fundamental particles of matter.
The plum pudding model best represents J.J. Thomson's mental image of an atom. In this model, electrons are embedded within a positively charged "pudding," similar to how seeds are embedded in a watermelon.
THE FIRST SCIENTIST WAS RUTHERFORD.
This is the quantic model of atom.
A model of the atom is a 3-D structure of the atom's structure.
John Dalton
The Bohr model of the atom was a planetary model.
J.J. Thomson, a British physicist, first proposed the plum pudding model of the atom in 1904. This model described the atom as a positively charged sphere with electrons embedded in it, similar to the seeds in a plum pudding.
Niels Bohr proposed his model of the atom in 1913, which is known as the Bohr model. This model introduced the idea of quantized energy levels for electrons in an atom, revolutionizing our understanding of atomic structure.
Ernest Rutherford created the nuclear model of an atom!
