How many electrons does it have, and what is its mass number? How many protons and neutrons are in an isotope with the symbol 13756Ba? State its mass number. An isotope has a total of 46 neutrons and 22 protons. What would be the atomic symbo...
Why is a nucleus with too many neutrons unstable? Unstable nuclei become more stable by spontaneously undergoing a change in their nucleus and emitting radiation. What is the term used to describe this process? Fission reactions are induced in nuclear power plants because they produce great amount...
You make an even larger, unstable radioactive isotope of uranium, uranium-236, that promptly splits into two smaller and more stable atoms krypton and barium (3). In the process, heat energy is released and there are three spare neutrons left over (4). The neutrons can go on to react ...
The periodic table, also called the periodic table of elements, is an organized arrangement of the 118 known chemical elements. The chemical elements are arranged from left to right and top to bottom in order of increasing atomic number, or the number of protons in anatom's nucleus, which ge...
Nuclear reactions are those that cause changes to the nucleus of an atom. Because the nucleus contains protons and neutrons, the change in these will either cause changes to the identity of the element and/or a change to a different isotope of the same element....
In alpha decay, a nucleus will emit an alpha particle. Alpha particles have a very low penetrating power and can be blocked by a piece of paper, clothing, or skin. However, if the alpha particles are inhaled or ingested, they can be quite toxic....
The beta decay is the decay of electron or positron from a radioactive nucleus. The atomic number of an atom is the number of protons present in the nucleus and the mass number is the total number of protons and neutrons present in the nucleus....
n. (a) How many neutrons are produced? (b) If the initial kinetic energy of the neutron isHow many joules of energy would be released from the fissioning of 1 kg of ^{235}U, assuming 198 MeV energy released per fi...
