Explain what makes an isotope radioactive. Why do radioactive isotopes undergo radioactive decay? How does the energy released by nuclear reactions compare to that released by ordinary chemical reactions? Why? What is an example of nuclear chemistry, and how is...
What makes a radioactive decay chain end? What kind of radioactive decay does not cause transmutation? When polonium-210 decays by alpha radiation, what isotope is formed? What particles are the result of the decay of a free (not in a nucleus) neutron?
Isotopes are elements that have the same atomic number (which - as stated above - is what makes them the same element) but different Mass Numbers (A), due to different numbers of neutrons in their nuclei. For more about this see What is an isotope ?See also more words related to the...
Zircon is immune to weathering which makes it useful for relationship geological occasions in ancient rocks. During metamorphic events, zircon crystals may form multiple crystal layers, with each layer recording the isotopic age of an event, thus tracing the progress of the a quantity of metamorphic...
Most of an atom is empty space. If an atom were about as big as a baseball stadium, the nucleus would be the size of a pea in the very center and the electrons would be somewhere on the outside edge.What makes an atom of gold different from an atom of iron is the number of ...

This makes it particularly interesting to explore how AF might address these challenges. Another complicating factor is the evolutionary constraints derived from MSAs of IDPs and IDRs, which are often limited due to sequence hypervariability [Citation101–103]. Evaluations have been conducted to ...
The proton is a basic component of all atomic nuclei and the nucleus of the protium isotope of hydrogen. Positron (particle) The antimatter equivalent of an electron, having the same mass but a positive charge The notion of a positron weapon remains the stuff of science fiction. Proton (...
