atomic theory timeline has no followers yet. Be the first one to
could not explain the of sublevels within higher energy levels.
could not explain the nature of electrons and neutrons.
to include the bright line spectra in hot gases and absorption spectra in cold gases
came up with atomic model
The day he came up with his atomic model
to account for the alpha particles that deflect and reflect off of gold foil
many electrons within energy shells.
radiation between the energy shells.
each energy level has a fixed amount of electrons.
atomic theory model
Could not explain for the amounts of radiation.
At the centre of every atom there us a positively charged nucleus.
The majority of the mass of an atom is the nucleus.
didn't know about the emission specter of element.
thomson was indeed able to work out a quantitative relationship between the charge and the mass of the negatively charged particles.
Electrons produce the identical cathode ray particles, which are even smaller than the smallest of atoms.
All atoms contain electrons that rotate around the atom.
He came up with his atomic theory
To figure out why atoms move the way they do
Contained many inaccuracies, about the masses about atoms
All matter is made up of small particles called atoms.
Atoms cannot be created, destroyed, or divided into smaller particles.
