and polonium - the rays she

that are invisible and indestructibleJames Chadwick- discovered neutrons - neutrons are located
in the center of an atomErnest Rutherford- Discovered nucleus
of the atom - demonstrated that
the atom has a tiny and heavy nucleusJ.J. Thomson- identified the heredity
nature of red-green colorblindness -
proposed a theory that all matter is

the law of constant compensation ,
the law states that if a compound
is broken down the
masses will have the same
proportions regardless
of the original substanceNeils Bohr- proposed a theory for the
hydrogen atom based on
quantum theory- stated that
electrons should move around
the nucleus only in prescribed orbits.Michael Faraday- discovered
electromagnetic induction, he believed that
the atom had more than
just negatively charged
they had another electrical component.Erwin Schrodinger-his wave equation
is used to find the allowed
energy level of quantum
mechanical systems, such as atoms.Antoine Lavoisier- discovered the role
oxygen plays in combustion,
the first person to make g
ood use of balancePériodes
Robert Millikan-discovered the
study of elementary electronic charge
and the photoelectric effect, the
electrons are what helps atoms
stick together
