The last kind of radiation is electromagnetic radiation, like X-rays and gamma rays. They are probably the most familiar type of radiation because they are used widely in medical treatments. These rays are like sunlight, except they have more energy. Unlike the other kinds of radiation, there is no mass or charge. The amount of energy can range from very low, like in dental x-rays, to the very high levels seen in irradiators used to sterilize medical equipment.
What is the electrical charge of a hydrogen atom? All atoms have no charge. Their charge is zero. Theyâre charge-neutral. There is exactly the same number of electrons and protons in an atom. Electrons have a charge of â[math]-e[/math]â and protons a charge of â[math]e[/math]â, where [math]e[/math] is the elementary charge and is [math]1.60217662 Ã 10^{-19}[/math] coulombs. So their charges cancel out.
