Dalton's theory was based on the principal that the atoms of different elements that could be distinguished by differences in their weights. In 1803, at the Royal Institution He stated this theory.
Thomsons model (plum pudding model of negatively charged particles in a positive soup) differed from Daltons model. Dalton hypothesised that atoms were indivisible, the word atom comes from the Greek atomos cannot be cut)
no, because according to him an atom is a tiny indestructable sphere with mass on it.
A Dalton's model of atom doesn't exist. Dalton principles are not in agreement with the discovery of isotopes and nonstoichiometric compounds.
The 2 protons in a helium atom would have a total of approximately 4 daltons. Each proton has a mass of approximately 1 dalton.
The Bohr model for hydrogen is a proton orbited by an electron.
Dalton's model of an atom, proposed in the early 19th century, viewed the atom as a solid, indivisible sphere. He believed that atoms of different elements had different masses and sizes, and that they combined in simple whole number ratios to form compounds. However, this model was later replaced by more advanced atomic models that better explained the behavior of atoms.

thomas discovered that the atom contained smaller particals called electrons

Dalton described atoms as solid spheres. Thomson discovered the the atom also contained negatively charged particles called electrons distributed in such a way that the atom had no charge.
You are PROBABLY referring to the "Bohr Model" of the atom.

The wave model of an atom was proposed by Erwin Schrödinger in 1926 as part of the development of quantum mechanics. Schrödinger's wave equation described the behavior of electrons in an atom as standing waves.
equal to the atomic mass of the element expressed in daltons. It is essentially the mass of one mole of the element in grams.
Thomson described this method. He gave plum pudding model.
