What is a nucleus in nuclear physics? Where are neutrons located? What makes up the nucleus of an atom? How many quarks are there in a helium-4 nucleus? Does the number of neutrons change in alpha decay? How does a cyclotron produce protons?
How many neutrons are in argon? What is potassium-argon dating used for? What state of matter is argon? What is the electronegativity of argon? What is tellurium used for? What group is argon in on the periodic table? Is argon a greenhouse gas?
many, many billions of times stronger thangravity, in fact [source: Bryson]. Despite the strength of strong force, it's possible to split a nucleus -- by shooting neutrons at it. When that's done, a whole lot of energy is released. When atoms split, their particles smash into nearby ...
Physicists came up with the idea of strange matter in the 1970s when they wondered what would happen if protons and neutrons were squished superhumanly hard [source: Freedman]. Let's repeat a similar version of their theoretical experiment, imagining we have an iron atom, plus a ...
example,carbon atomsalways have six protons;hydrogen atomsalways have one; andoxygen atomsalways have eight. Different versions of the same element, called isotopes, can have a different number of neutrons. Elements can also gain or lose electrons to become charged, in which case they are called...
Everything we do is controlled and enabled by electrical signals running through our bodies. As we learned in intro physics, everything is made up ofatoms, and atoms are made up of protons, neutrons and electrons. Protonshave a positive charge,neutronshave a neutral charge, andelectronshave a...
Atoms may have an equal number of protons and neutrons. If, however, there are too many or too few neutrons, the atom is unstable, and it sheds particles until its nucleus reaches a stable state. Think of the nucleus as a pyramid of building blocks. If you try to add extra blocks to...
Besides hydrogen, what element wants 2 valence electrons in its outer shell? How many neutrons, protons, and electrons are in carbon? How do you tell the valence charge or electron of a transition metals` atom ? ( to balance it out with another atom ) ...
