A proton is a positive particle with a mass of approximately 1 Dalton. It is found in the nucleus of an atom and carries a positive electric charge.
The scientist who first proposed the idea of the atom as a hard solid ball was John Dalton in the early 19th century. Dalton's atomic theory described atoms as tiny, indivisible particles that made up all 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.
A plum pudding model with negatively charged electrons embedded in a positively charged sphere.
Dalton discovered the particles that make the atom and the atom itself
Dalton didn't discover the atom. Democritus did. Dalton, however was the first to use the word atom. which comes from the GGreek word atomos, meaning "cannot be split"
Thompson described his model as plum pudding. Since not many people even know what plum pudding is, i like to describe his model as a scoop of chocolate chip ice cream. Imagine the vanilla ice cream as the positive material and the chips as the negative material.
john dalton didnt find the atom democrites did... john dalton was reading and found the word atomos in a journal and decided he would change the name to atom meaning undivisible.
