Radioactivity is the disintegration of an unstable atom's nucleus into a more stable energy-wise nucleus. This process occurs spontaneously and... Learn more about this topic: Radioactivity | Definition, Types & Uses from Chapter 18/ Lesson 7 ...

more massive than an electron. Atoms always have an equal number of protons and electrons, and the number of protons and neutrons is usually the same as well. Adding a proton to an atom makes a new element, while adding a neutron makes an isotope, or heavier version, of that atom. ...
A bit is a tiny section of a computer that either holds an electrical charge (1) or does not hold an electrical charge (0). A qubit is the uncertain, unstable position of an electron within an atom. What are the challenges of building quantum computers? To this point, very few quantum...
If an atom were about as big as a baseball stadium, the nucleus would be the size of a pea in the very center and the electrons would be somewhere on the outside edge.What makes an atom of gold different from an atom of iron is the number of protons, neutrons, and electrons inside...
All matter consists of atoms, which, in turn, consist of protons, neutrons and electrons. Both protons and neutrons are located in the nucleus, which is at the center of an atom. Protons are positively charged particles, while neutrons are neutrally charged. Electrons are negatively charged, ...
Quarks are fundamental particles, also known as elementary particles, that form composite particles located in the nucleus of the atom. They can also combine with antiquarks to form mesons.Answer and Explanation: An up quark is a type of elementary particle that binds with other quarks to form...
An atom's proton number is its atomic number on the periodic table and determines the identity (name) of the element. Some atoms can gain or lose neutrons while continuing to happily exist, but if a nucleus loses or gains a proton instead, it's a game-changer, because now whatever the...
What is released when an electron loses energy? Energy: Atoms absorb and lose energy. Generally, it's the electrons that absorb and lose energy. The energy absorbed by an electron in the first energy level making it jump up to the next energy level is 10.2 electron-volts (eV). ...
When a free electron scatters from an atom, is it correct to think of this as an exchange of virtual quanta between the free electron and the bound electrons and protons in the atom? If that is the case, how does one calculate the spectrum of virtual quanta exchanged during the coll...
