Answer

1: electron; 2: plum pudding

Explanation

JJ Thomson, the British scientist, had conducted some experiments where he discovered the existence of tiny particles in atoms. He named these particles electrons. This crucial discovery by J.J. Thomson led to the conceptualization of an atomic model. The model he proposed is better known as the plum pudding model. So, the options that best fits are 'electron' for (1) and 'plum pudding' for (2).
