Electrons form a spinning cloud around the nucleus. Protons and neutrons make up the mass of atoms. Electrons, miniscule compared to the protons and neutrons, contribute very little to the overall mass of atoms.Atoms and Isotopes Atoms of the same element have the same number of protons. All...
How Nuclear Radiation Works describes protons, neutrons and electrons in some detail. For example, hydrogen atoms have one electron orbiting the nucleus. Helium atoms have two electrons orbiting the nucleus. Aluminum atoms have 13 electrons circling the nucleus. Each atom has a preferred number of ...
How Many Neutrons and Protons Can Get Along? Maybe 7,000Clara Moskowitz, SPACE.com
When trying to find the number of neutrons, protons or electrons that different chemical species have, the periodic table is your best friend. Take a look at how to use the periodic table as well as nuclear notation to find the number of subatomic particles associated with any chemical species...
For example, there are three types of potassium atoms that occur naturally. All three types contain 19 protons and 19 electrons. 钾元素在自然界中有三种原子。三种原子都含有19个质子和19个电子。 However, one type of potassium atom contains 20 neutrons, another 21 neutrons, and still another 22 ...
These particles, made up of protons and neutrons, are large and can only travel a short distance -- in fact, they can be stopped with just a piece of paper or even your skin. However, inhalation or ingestion of alpha particles can be very dangerous. Once inside your body, alpha ...

If you know the atomic number and the mass number of an isotope of an element, how can you determine the number of protons and neutrons?Answer and Explanation: The atomic number is equal to the number of protons in an atom. For ...

This simple atom consists of a nucleus (containing the protons and neutrons) and an electron cloud. It's helpful to think of the electrons in this cloud circling the nucleus in many different orbits. Absorbing Energy Absorption of energy: An atom absorbs energy in the form of heat, light ...
