How many electrons are in the highest occupied energy level of barium? Why doesn't ethane and water react? Most companies that use any version of exponential smoothing use fairly small smoothing constants such as 0.1 or 0.2. Explain why they don't tend to use larg...
How many electrons are in the highest occupied energy level of barium? How do electrons move in a battery? Why are polyatomic ions not neutral? Do all atoms achieve octet when they bond? For a one-electron atom or ion, spin-orbit coupling splits all states except s...
Uranium-236 is too unstable to hang around for long so it splits apart into two much smaller atoms, barium and krypton, releasing quite a lot of energy and firing off three spare neutrons at the same time.Now the brilliant thing is that the spare neutrons can crash into other uranium-...
