1. the development of the cathode ray tube led to the discover of what subatomic particle?
2. what model of the atoms proposes that electrons are located in orbitals?
3. what terms refers to the region of an atom where electrons are most likely to be found?
4. what are the results and conclusion for gold foil experiment?
5. which orbital has the least amount of energy?
6. compare the energy between 1st and 3rd orbitals.

1. Protons

2.Neil Bohr model

3.shell

4.results and conclusion for gold foil experiment

   The protons are not scattered uniformly but they are concentrated at the nucleus (core)  of the atom

 The nucleus is largely responsible for the entire mass of the atom.

There is an empty space surrounding the nucleus and the electrons revolve round an orbit at a distance from the nucleus

5. the s orbital has the least amount.

Explanation:

the maximum capacity for s orbital is 2.
