To determine which of the elements listed (sulphur, selenium, tellurium, and polonium) are not radioactive, we can follow these steps:1. Understand Radioactivity: Radioactivity is the process by which unstable atomic nuclei los

“actinides” — elements that were discovered relatively late in history. Like all other actinides, uranium is “radioactive” – it decays over time and releases energy in the process. Its special properties make uranium the main source of fuel for nuclear reactors — a chicken-egg sized ...
In 1896, Madame Curie began to4on radioactive elements with her husband and in a little room5of them worked day and night, After two years of hard work , at last ,6December 26, 1898 , they7that they8radium. This is another kind of element which has still9radioactivity than uranium. ...
The labels most commonly employed for these studies are radioactive elements, enzymes, chemicals which fluoresce when exposed to ultraviolet light, and others. A number of fluorescent materials are known and can be utilized as labels. These include, for example, florescein, rhodamine, auramine, Tex...
