what percentage of the atom is empty space?
Every atom in your body was once part of the cosmos. The next time you look up at the night sky you might want to meditate on this fact. You and the universe are one. You are 99% empty space. The elements we just referred to are composed of atoms, and those atoms make up your entire body. One percent of every atom is composed of protons, neutrons, and electrons. The other 99% is empty space. To put this in perspective, imagine at atom the size of a football stadium. Place an orange in the center to represent the approximate size of the nucleus.
