Answer: option D. Atoms containd small negatively charged particles that are called electrons.

JJ Thompson carried out three important experiments with cathode rays. With them he proveed that cathode rays were negative charged particles and that the ratio charge/mass was so large that the particles either had a huge charge or had a very small mass, and he came up with the latter, defining that these negative charged particle were very small.

Answer:

Me and my friends were going to do a science experiment. Jonny’s job was to make the HYPOTHESIS. He said the “ If we mix baking soda and vinegar together, the TEMPERATURE will go down.”

So then Molly mixed the baking soda and vinegar together and checked the TEMPERATURE. We all OBSERVED as the thermometer’s TEMPERATURE went down. “ your THEORY/ HYPOTHESIS was correct!” Exclaimed Molly.

Then the whole science GROUP let out with a cheer! And wrote the information down on their EXPERIMENTAL info chart. They took a microscope and looked at the mixture because they wanted to the the little PARTICLES in the mixture. Lily CONTROLED the microscope she zoomed in and out to see the particles.

Explanation:

i hope this helps:)
