This would support Dalton's postulates that says atoms are indivisible because there are no smaller particles than the atoms.
Explanation:
If during Thomson's cathode rays experiment, the size of the particles produced is the same as the size of the atom forming the cathode, it would perfect corroborate with Dalton's postulate.
- John Dalton believed the simplest substance of any matter is an atom.
- An atom is indivisible and cannot be broken down.
- From his atomic theory, matter does not any other smaller particles besides atom.
- If the size of the atoms of rays and that of the cathode were to be the same, this would have supported his claim.

Answer:
Groups 14, 15, and 16 have 2,3, and 4 electrons in the p sublevel (p sublevel has 3 "spaces" AKA orbitals), because Hunds says one in each orbital before doubling up if you had 2 electrons, group 14, they would both be in the first orbital, with 3 electrons, group 15, two in the first orbital one in the 2nd none in the 3rd. With 4 electrons, group 16, then you would have 2 in the first 2 orbitals and NONE in the 3rd.
Explanation:
If you are in group 13 you only have 1 electron so it can only be in one orbital. with group 17, you have 5 electrons, so 2 in the first 2 in the second and 1 in the 3rd, correct for Hunds rule anyway. Noble gasses, group 18, have 6 elecctrons, so every orbital is full any way you look at it.
