Question

Which best describes a way that an experiment contradicted an existing model of the atom?


Thomson showed that neutrons must be located in the center of an atom.
Rutherford showed that the atom must have a nucleus.
Bohr showed that atoms must contain negative charges.
Chadwick showed that atoms cannot contain neutral particles.

Answer 1

This is b)

Answer 2

Why thank you kind sir :)

Answer 3

D)is wrong, because Chadwick found neutrons.
Thomson did not know about neutrons.
Bohr explained energies of electrons from
Experimental spectres.

Answer 4

Rutherford made an experiment with alpha particles and gold foil.
Some LPGA particles bounced back, so there have to be a solid nucleus in gold.

Answer 5

Alpha, not LPGA! Sorry!
