How many neutrons, protons, and electrons are in carbon? How can I tell if a molecule is polar or non-polar? For a one-electron atom or ion, spin-orbit coupling splits all states except s states into doublets. Why are s states exceptions to this rule...
These particles, made up of protons and neutrons, are large and can only travel a short distance -- in fact, they can be stopped with just a piece of paper or even your skin. However, inhalation or ingestion of alpha particles can be very dangerous. Once inside your body, alpha ...
The neutrons are neutral. Their purpose in the nucleus is to bind protons together. Because the protons all have the same charge and would naturally repel one another, the neutrons act as "glue" to hold the protons tightly together in the nucleus. Behave, Atom The number of protons in the...
Plutonium generally isn't found in nature. Trace elements of plutonium are foundin naturally occurring uranium ores. Here, it is formed in a way similar to neptunium: by irradiation of natural uranium with neutrons followed by beta decay. Primarily, however, plutonium is a byproduct of the n...
If you know the atomic number and the mass number of an isotope of an element, how can you determine the number of protons and neutrons? How do you tell how many valence electrons there are in an element by looking at the periodic table? How do the electrons help in pre...
