Learn about the parts of an atom, their mass, and their charge, in this video from the Properties of Matter chapter FuseSchool Chemistry. 0:00:01,220 -- 00:00:07,500 we already know that atoms are really 00:00:04,050 -- 00:00:09,389 small but we can get smaller if we zoom 00:00:07,500 -- 00:00:12,509 into an atom we find that is made up of 00:00:09,389 -- 00:00:16,080 protons, neutrons and electrons and a lot 00:00:12,509 -- 00:00:18,780 of empty space. Imagine an Olympic 00:00:16,080 -- 00:00:21,420 swimming pool: 50 metres wide, this is our 00:00:18,780 -- 00:00:24,180 atom. At the centre of our atom is the 00:00:21,420 -- 00:00:27,810 nucleus, the nucleus is made up of 00:00:24,180 -- 00:00:30,300 protons and neutrons but if we jumped 00:00:27,810 -- 00:00:32,189 into the pool to find the nucleus it 00:00:30,300 -- 00:00:36,780 would be pretty much impossible because 00:00:32,189 -- 00:00:38,880 it is a size of a grain of sand. Around 00:00:36,780 -- 00:00:4
