Write out the electron configuration for samarium (Sm). How many unpaired electrons does it have in the ground state? Write the electron configuration for scandium. How many unpaired electrons does it have in the ground state? Write the electron configura...
How many electrons does cobalt have? Cobalt Cobalt is a transition metal that is located in the first row of the transition metals. Its atomic mass is 58.933 g/mole and is used to make blue pigments. The largest mining operations for cobalt are in Central Africa. ...
Aluminum atoms have 13 electrons circling the nucleus. Each atom has a preferred number of electrons zipping around its nucleus. Electrons circle the nucleus in fixed orbits -- a simplified way to think about it is to imagine how satellites orbit the Earth. There's a huge amount of theory ...
The interaction between electrons and holes in this setup has an interesting side effect – it generates light! How Can a Diode Produce Light? Light is a form of energy that can be released by an atom. It's made up of many small particle-like packets that have energy and momentum but ...

One way to measure and compare a magnet's "strength" is to see how many staples it can pick up. What is the difference between an iron and an aluminum core for the magnet? For example, roll up some aluminum foil tightly and use it as the core for your magnet in place of the nail...
When we switch on the power, the copper sulfate solution splits into ions (atoms with too few or too many electrons). Copper ions (which are positively charged) are attracted to the negatively charged brass electrode and slowly deposit on it—producing a thin later of copper plate. Meanwhile...
