Pair the atomic structure with the appropriate description

Draggable item		Corresponding Item
Protons		The dense center of the atom
Neutrons		Negatively charged particles around the nucleus
Electrons		Positively charged particles in the nucleus
Nucleus		Neutral particles in the nucleus

Match the scientist to the correct idea or experiment about atomic structure they contributed

Draggable item		Corresponding Item
Niels Bohr		Discovered the nucleus using his gold-foil experiment
J.J. Thomson		Proposed that electrons orbit the nucleus in specific layers
Ernest Rutherford		Identified the electron, leading to the 'plum pudding' model

John Dalton, in his atomic theory, proposed that atoms can be destroyed in chemical reactions.

True

False

Ernest Rutherford's gold foil experiment proved that an atom is mostly empty space with a dense center, now known as the nucleus.

True

False

J.J. Thomson is credited for the discovery of the electron through his cathode ray experiments.
