The number of ions in a compound depends on the structure of the compound and the oxidation states of the elements within the compound. An element's oxidation state is the number of electrons that an atom possesses or lacks relative to the number of protons in its nucleus. This determines t...

To calculate the maximum number of electrons in each energy level, the formula 2n2can be used, wherenis the principal energy level (first quantum number). For example, energy level 1, 2(1)2calculates to two possible electrons that will fit into the first energy level. Second Quantum Number...
An electron is a charged particle spinning on an axis and therefore has magnetic properties. This quantum number is not related to n,l, ml, and can have only two possible values: +1/2 or -1/2. The addition of the fourth quantum number allows electrons to fill into orbitals without brea...
From the small AA batteries used in your TV remote to large, industrial power stations that pull electricity directly from a grid, if it stores and transfers electrons, then it can power an electromagnet. Let's start with a look at how household batteries function. Most batteries have two ...
In general, the point of a relay is to use a small amount of power in the electromagnet -- coming, say, from a small dashboard switch or a low-power electronic circuit -- to move an armature that is able to switch a much larger amount of power. For example, you might want the el...
There are holograms on most driver's licenses, ID cards and credit cards. If you're not old enough to drive or use credit, you can still find holograms around your home. They're part of CD, DVD and software packaging, as well as just about everything sold as "official merchandise...
They're skeptical of it being made by heavy atoms, which are hurled through space by violent astrophysical processes, hitting other heavy atoms in the process [source: Jaffe]. Edward Farhi, an MIT physicist who researched strangelets, thinks the most likely place to find strange matter is in...
By gaining or losing electrons. Theflow of electronsbetween atoms is what we call electricity. Since our bodies are huge masses of atoms, we can generate electricity. When we talk about the nervous system sending "signals" to the brain, or synapses "firing," or the brain telling our hands...
