Question

match each scientist to their discovery regarding the atom. rutherford millikan thomson dalton atoms are indivisible. atoms have a positive nucleus. atoms contain electrons. electrons have a charge of -1.

Explanation:

• Rutherford: Through the gold - foil experiment, he proposed the nuclear model of the atom where atoms have a positive nucleus.
• Millikan: Performed the oil - drop experiment to determine the charge of an electron (\(e=- 1.6\times10^{-19}\ C\)).
• Thomson: Discovered electrons in cathode - ray tube experiments and proposed the plum - pudding model of the atom.
• Dalton: His atomic theory stated that atoms are indivisible (though later proven incorrect in some aspects as sub - atomic particles were discovered).

Answer:

Rutherford - Atoms have a positive nucleus.
Millikan - Electrons have a charge of -1.
Thomson - Atoms contain electrons.
Dalton - Atoms are indivisible.
