Photosynthesis is the process that plants use to convert sunlight into chemical energy that can used to power their growth. Jan Ingenhousz was a Dutch scientist who was studying the process of plant respiration. He observed that when he placed a plant in a dark room, the plant would still produce oxygen gas. He realized that the plant must be using some other process to produce oxygen and also that process was photosynthesis.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Discovery_of_Electron\"><\/span>Discovery of Electron<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The discovery of the electron credited to J.J. Thomson who in 1897 experimentally determined the mass-to-charge ratio of the electron. Thomson&#8217;s experiment consisted of passing a beam of electrons through an electric and a magnetic field. Therefore he observed that the beam deflected and that the amount of deflection was dependent on the electron&#8217;s mass-to-charge ratio. This ratio is now known as the electron&#8217;s velocity.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Discovery_of_Proton\"><\/span>Discovery of Proton<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>In 1897, J.J. Thomson discovered the proton. Thomson found that cathode rays (a stream of electrons) could deflected by a magnetic field. He reasoned that if the cathode rays were negatively charged, then they must made up of smaller particles that were positively charged. He called these particles &#8220;protons.&#8221;<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Discovery_of_Neutron\"><\/span>Discovery of Neutron<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The discovery of neutron credited to James Chadwick in 1932. He was working on the theory of the neutron and was trying to find a way to detect them. However he found that by using beryllium and alpha particles, he could create a reaction that would produce neutrons.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What are Subatomic Particles?
