Answer;
Thomson's experiments are important because they showed that the atom is clearly composed of smaller particles.
Explanation;
J.J. Thomson used magnetic and electric fields to measure the mass-to-charge ratio of a cathode ray particle. Thomson set out to prove that the cathode rays produced from the cathode were actually a stream of negatively charged particles called electrons.
J.J. Thomson's experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. He proposed the plum pudding model of the atom, which had negatively-charged electrons embedded within a positively-charged "soup."
According to the U.S. Geological Survey, most of that three percent is inaccessible. Over 68 percent of the fresh water on Earth is found in icecaps and glaciers, and just over 30 percent is found in ground water. Only about 0.3 percent of our fresh water is found in the surface water of lakes, rivers, and swamps. The use for the water in the world is for household drinking water. The ocean stores about 97 percent of the Earth's water; the remaining three percent is stored in glaciers and ice, below the ground, in rivers and lakes. Of the world's total water supply of about 332 million cubic miles of water, about 97 percent is stored in the ocean.
