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 aluminum have? How many valence electrons does an atom of Al possess? How many valence electrons are in a neutral atom of argon? How many valence electrons are in a neutral atom of silicon? How many valence electrons does a neutral atom of silicon have? How ma...
How many electrons are in the 3rd orbital of copper(I) ions? What is the oxidation number of fluorine in XeF4? How many electrons are in a Cu2+ ion? How many electrons are in the Mg2+ ion? How many electrons does the Ni2+ ion have? how many electrons are in nitride? How many p...
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 ...
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...

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...
P-type semiconductors are extrinsic semiconductors that have more holes than electrons, and are made by doping an intrinsic semiconductor with impurities like boron, indium or aluminum. In “p-type,” the “p” stands for “positive,” as the semiconductor has a majority of positively-charged ...
Many have a frosted outer plastic case or "diffuser" to spread the bright, highly directional flashlight glare of their little LEDs into a warmer, fuzzier glow more suitable for home lighting.How LED lamps work One LED would normally run off something like a 1.5-volt DC (direct current) ...
