simple experiments
_____ / 3pts.
Niels Bohr
Cathode ray tube
a. An English chemist, __________________ used ______________________ to
determine certain characteristics of atoms.
b. ____________________ used ____________________________ to discover that
atoms contain negatively charged particles called electrons.
c. ________________________ used ______________________ to discovered the
positively charged nucleus and the identification of protons.

in orbits. Later this was revised again to support the cloud model, suggesting electrons
are found in orbitals outside the nucleus.
