Question

Whose work directly resulted in the development of and atomic model that has negative electrons stuck within a sea of positive materials

Answer 1

J.J. Thomson

Step-by-step explanation:

J.J. Thomson's worked on cathode rays and proved that they are negatively charged particles. According to J.J.Thompson's model the electrons are like plums embedded in a sea of positive charge which is akin to the pudding. Thompson's model was proved incorrect after Rutherford discovered the nucleus.

Answer 2

It is the work of J.J Thomson that directly resulted in the development of an atomic model that has negative electrons stuck within a sea of positive material. His proposal was called the plum pludding model. He is the one who discovered electrons.
