Structure of an Atom If you look inside an atom, you find tiny particles called protons, neutrons, and electrons. Atoms of each element have different numbers of these particles. Protons and electrons have electrical charges. You can think of this as being similar to a battery, which has a...

than the number of protons, with this disparity becoming larger as atomic number increases. A hydrogen atom, for example, has a proton but no neutrons, while a helium atom has two of each. Tin, on the other hand, has 50 protons and 69 neutrons, while uranium has 92 and 146 ...
So, hydrogen has 1 proton, oxygen has 8 protons, iron has 26 protons, and so on. The number of neutrons is usually fixed for a particular atom (for example, the most common form of carbon has 6 neutrons), but this does not have to be so. How much of human body is empty space?
The total number of protons and neutrons added together is called the relative atomic mass. Hydrogen has a relative atomic mass of 1, while helium's relative atomic mass is 4 (because there are two protons and two neutrons inside). In other words, an atom of helium is four times heavier...
