Which tenet of Daltons atomic theory did Thomson disprove?
Atoms cannot be divided into smaller particles.
Why do you think Thomson hypothesized that electrons must come from inside an atom?
Thomson had two pieces of evidence: 1- No matter what metal he used for the disk, the particles produced were indentical. 2- The particles had about 1/2000 the mass of a hydrogen, the lightest atom. These experiments provided the first evidence that atoms are made of even smaller particles.
How did Thomson help the understanding of atom?
He discovered that the atom contained smaller particles called electrons.
Which is a way that the model of the atom became more accurate due to new investigations?
Experiments showed that the atom is made up of smaller particles.
What did Thomson call electrons?
Thomson believed about atoms, that : An atom consists of a sphere of positive charge with negatively charged electrons embedded in it. Positive and negative charges in an atom are equal in magnitude, thus an atom is electrically neutral and it has no overall + or - charge.

What findings led JJ Thomson to infer that particles are smaller than atoms do exist?
Particles are smaller
What evidence supported Thomson's hypothesis that negative particles he observed came from inside atoms.?

How did the Thomson's experiment change Dalton's atomic model?
