If a few of the spaces aren't occupied, an atom seeks to acquire or share electrons to fill it to achieve a stable outer shell with eight electrons. On the other hand, it's easier for an atom with just a few extra electrons to get rid of them to achieve stability. The noble gases...
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. ...
Any two atoms that have the same number of protons belong to the same chemical element. But atoms with an equal number of protons can have a different number of neutrons, which are defined as being different isotopes of the same element. These isotopes are often unstable, and all those with...
We can think of the simplest case, a paradigmatic example for deterministic low dimensional chaos, as it happens, a fluid in an open tank heated from below and developing only one or two unstable modes into dissipative structures (Rayleigh-Bénard “rolls”) [66,67,68]. Letting such boundary...
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...
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...
