Answer and Explanation:1 Radioactivity is the disintegration of an unstable atom's nucleus into a more stable energy-wise nucleus. This process occurs spontaneously and... Learn more about this topic: Radioactivity | Definition, Types & Uses ...
What is the rate of radioactive decay? What causes an isotope to be radioactive? What makes an atom radioactive? How fast does a radioactive isotope decay? What isotope does americium-241 turn into after alpha decay? Explore our homework questions and answers library ...
Radioactivity is caused when an atom, for whatever reason, wants to give away some of its energy. It does this because it wants to shift from an unstable configuration to a more stable configuration. The energy that is released when the atom makes this shift is known as radioactivity. In ...
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 protons, neutrons, and electrons inside...
What element makes glowing signs? What chemical element is Sb? What synthetic elements are unstable? Where do elements come from? What are the types of native element minerals? What one characteristic of an atom determines what type of element it is?
Radioisotopes, or radionuclides, are unstable forms of elemental matter either man-made or found in nature. They all undergo a spontaneous process of radioactive decay through the emission of alpha and beta particles, gamma rays, and more. All of the elements on the periodic table with atomic ...
Radioactive Decay: Any two atoms that have the same number of protons belong to the same chemical element. But atoms with an equal number of protons can have a different number of neutrons, which are defined as being different isotopes of the same element. These isotopes are often unstable,...
Nuclear bombs involve the forces — strong and weak — that hold the nucleus of an atom together, especially atoms with unstable nuclei. There are two basic ways that nuclear energy can be released from an atom. In nuclear fission, scientists split the nucleus of an atom into two smaller fr...
Anything 95 and above has to come from a reactor or particle accelerator. During the early 2000s physicists at Russia’s Dubna facility began generating element 118, oganesson2, by fusing calcium and californium one atom at a time. All superheavies are radioactive and many are very short-...
The half-life of a radioactive species is the time it takes for half of the unstable nuclei in a sample to decay into a different form. This number can go very high, into the billions of years, although for carbon-14 it is about 5,730 years (a blip in geological time, if not in...
