Isotope Manufacturers Key Terms
Familiarize yourself with isotopes and their related terminologyBy Howard Robertson Isotopes are a different version of atoms in a chemical element. These atoms have nuclei with varying number of neutrons, but the same number of protons. The atomic mass of each of the isotopes is different, making them physically different from each other.
Most natural elements have isotopes that are stable in their behavior. Elements can also have radioactive or unstable isotopes. Usually, for a given element, isotopes have equal number of protons and electrons and display similar chemical behavior due to a similar electronic structure.
Read on to understand the isotope terms better.
Atom
An atom is the smallest, indivisible unit of an element that retains the properties of the element. It contains a positively charged nucleus and negatively charged electrons that orbit around it.

You can learn more about atoms at Jefferson Lab, a useful resource on scientific education.
Radioisotopes or radioactive isotopes
In an unstable atom, the nucleus keeps changing, becomes radioactive and remits alpha, beta or gamma rays until it can achieve stability. These become radioactive isotopes.
Try:
You can learn about radioactive isotopes at the NDT Resource Center, a resource on non-destructive testing and evaluation.
Kinetic isotope effect
The kinetic isotope effect or isotope fractionation refers to the dependency of the rate of a chemical reaction on the isotopic identity of an atom.

Get more information on the kinetic isotope effect at the University of Victoria (PDF) website.
Neutrons
Neutrons make up the nucleus of an atom along with protons. They stick together due to a strong nuclear force. Free neutrons are radioactive and they have no electrical charge.
Try:
At ISIS Pulsed Neutron & Muon Source, you can learn about neutrons and their history.
Protons
Protons are within an atom's nucleus along with neutrons. Protons have a positive electric charge and are generally stable. Quarks are smaller particles that form protons.

Electrons
Atoms consist of the nucleus and electrons. Electrons usually have a negative charge, but some positrons or positively charged electrons exist. Within an atom, electrons can have differing energy levels and depending on that, they absorb or emit photons.

Tips & Advice to help you make your decision on Physical Vapor Deposition (PVD) Coatings
Physical vapor deposition (PVD) coatings involve the use of a family of coating technologies for tool coating, decorative coating, and other machine coating operations. Basically, PVD technologies have three classes: evaporation, sputtering, and ion plating. When looking for the best method of PVD for your business, you need to consider a number of factors.
One factor is the type of material in which the technology will be applied. PVD coating is recognized as an acceptable substitute for electroplating and some painting applications. You can use a broad range of materials to coat a myriad of substrates.
If you value the importance of reducing hazardous wastes and materials ... more
Physical vapor deposition (PVD) coatings involve the use of a family of coating technologies for tool coating, decorative coating, and other machine coating operations. Basically, PVD technologies have three classes: evaporation, sputtering, and ion plating. When looking for the best method of PVD for your business, you need to consider a number of factors.
One factor is the type of material in which the technology will be applied. PVD coating is recognized as an acceptable substitute for electroplating and some painting applications. You can use a broad range of materials to coat a myriad of substrates.
If you value the importance of reducing hazardous wastes and materials in your industry, the PVD technology is a suitable alternative. This solution is generally suggested, though, for large-scale applications.
The speed of deposition is another factor. You should also determine the throwing power, the thickness scattering and rate of the deposition process. In general, when the throwing power is high, the ability of the process to coat objects with uneven surfaces will be better.
The main obstacle to the use of this technology is the huge initial investment. The installation of a new PVD technology will likely cost some hundred thousand dollars. Overhead cost, however, is essentially the same with electroplating. For more information on physical vapor deposition (PVD) coatings, visit the links on this Business.com page.
