An atom a fundamental piece of matter. ... An atom itself is made up of three tiny kinds of particles called subatomic particles: protons, neutrons, and electrons. The protons and the neutrons make up the center of the atom called the nucleus and the electrons fly around above the nucleus...

Electrons are not always confined to their specific shells. If an atom absorbs a photon of light with enough energy — say an ultraviolet photon from ahot star— this absorbed energy can cause an electron to transition to a higher energy level for a short time. This is an unstable situation...
tend to do that. The library on the campus featured huge glass windows on every floor. I could see Mark through the glass as he descended the steps from his fifth floor perch. I could also tell that as I walked towards the library, our paths would cross precisely at the library's fron...
together, generating nuclei with extra protons and neutrons. However, these ultra-heavy elements are highly unstable and difficult to make. “We really do not know what is the heaviest element that could exist,”Witold Nazarewicz,a nuclear physicist at Michigan State University, told Smithsonian ...
Alpha decay happens when the ratio of neutrons to protons is so imbalanced that the nucleus of the atom is unstable. This typically involves atoms... Learn more about this topic: Radioactive Decay | Formula, Types & Examples from Chapter 22/ Lesson 7 ...
The three types of ionizing radiation we're going to discuss here are alpha particles, beta particles and rays. Particulate radiation involves fast-moving, small particles that have energy and mass. When an unstable atom disintegrates, it produces particulate radiation, including alpha and beta part...
How do electrons move in covalent bonds? Covalent Bonds These types of bonds occur most often in non-metals. There are mainly three types: single, double, and triple. When only one electron from each atom is shared between atoms, it is known as a "single covalent bond." When two electro...
The nucleus will absorb the neutron without hesitation, become unstable and split immediately. As soon as the nucleus captures the neutron, it splits into two lighter atoms and throws off two or three new neutrons (the number of ejected neutrons depends on how the U-235 atom happens to ...
Do not light fires or outdoor grills during these times. Keep the engine of your car or boat tuned. Make sure that your tires are properly inflated. Use environmentally safe paints, cleaning and office products (some of these chemicals are sources of VOC). Conserve energy. Besides pe...
