Give the element symbol, atomic number, number of protons, number of neutrons, mass number, and total number of electrons for cesium-135. How many electrons, protons, and neutrons are found in isolated atoms having the atomic symbol 17/8O? How many el...
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...
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 ...
many are only effective if the radiation is coming from a single localized source. They can be confused by multiple sources or those that are spread out in space, while the “Tetris”-based version can handle these situations well, adds Xue, co-lead author of the work. ...
It has been suggested that extremely neutron rich nuclei constitute a second branch of the table of isotopes whose ground states have the maximum possible isospin Tmax = A/2 and that neutral members of the T max branch (i.e., polyneutrons) serve as mediating particles for the new class ...
How many 3d electrons are found in the below element? nickel, Z = 28. A monatomic ion has a charge of +1. The nucleus of the ion has a mass number of 85. The number of neutrons in the nucleus is 1.30 times that of the number of...

Neutrons also weight one atomic unit, but have no charge. They are responsible for "gluing" the nucleus together, ensuring that the positive charges on the protons do not repulse strong enough to disintegrate the atom Electons have virtually no weight, and a negative charge. These are relati...
That is, it should have 6 protons and 6 neutrons in its nucleus. However, when the number of neutrons is 8 producing a carbon-14 isotope, the nucleus will be highly unstable and has to undergo radioactive decay. Carbon-14 can be referred...
Each chemical element has its own distribution of isotopes, which are atoms with the same number of protons, but differing numbers of neutrons. Some of these isotopes are unstable, which are indicated with half-life values in the literature. The half-life c...
