Changes in the Atomic Model Flashcards

All 4 cards in this deck

What can cause a scientific model to be changed or replaced?

New experimental evidence that the existing model cannot explain.

Name, in order, the atomic models from the indivisible sphere to Bohr's model.

Indivisible sphere → plum pudding model → nuclear model → Bohr model.

True or false? Scientific models of the atom stay the same once experiments have supported them.

False. New experimental evidence may lead to a model being changed or replaced.

Which experiment provided the evidence that led to the nuclear model of the atom?

The alpha particle scattering experiment.
