Science Made Simple: What Is Radioactivity?
Radioactivity is the release of energy from the decay of the nuclei of certain kinds of atoms and isotopes. Atomic nuclei consist of protons and neutrons bound together in tiny bundles at the center of atoms. Radioactive nuclei are nuclei that are unstable and that decay by emitting energetic particles such as photons, electrons, neutrinos ...

Glossy Or Matte: What Should I Know About Each Type Of Coated Paper
Both coated paper types are made from the same chemical coating. The difference lies in how much coating is on each type of paper. Matte paper will have enough coating to make a paper look smooth, but not enough to be reflective. Glossy paper will have a thicker coating that makes it shine, but it can definitely cause smudges, fingerprints, and ...

How & When to Use Glossy Paper
1. High Gloss. High gloss paper is the shiniest, glossiest paper you can get. High gloss paper provides vibrant, rich color reproduction, as well as the crispest resolution, but it can be difficult to view under bright lights because it can reflect that light and cause glare. 2. Semi Gloss.

11.1: Radioactivity
There are three main forms of radioactive emissions. The first is called an alpha particle, which is symbolized by the Greek letter α. An alpha particle is composed of two protons and two neutrons, and so it is the same as a helium nucleus. (We often use He4 2 to represent an alpha particle.) It has a 2+ charge.
