Radioactive elements
Many physical terms have appeared in physics, the most important of which are radioactive elements, which are the elements whose nucleus is unstable movement as a result of the increase in the number of protons and neutrons in it. Of the rays, which are alpha, beta, and gamma rays, the discovery of these radioactive elements or with natural radioactivity is due to the French scientist Henri Bakrill in 1896 AD, who discovered the elements of uranium and thorium, and with this discovery there has become a revolution in the identification of the radioactive elements that have become used in Treating and diagnosing diseases, and in power generation, among others.
Radioactive elements in nature
Uranium
This element is classified in the periodic table of the elements in the actinide series, and the atomic number of this element is 92, as the atom contains 92 protons and 92 electrons, and this mineral, whose color tends from white to silver, is found in soil and rocks. Long-range bombers, as well as in installations that rely on nuclear energy, such as stations that generate electricity, desalinate sea water, as well as in estimating the age of igneous rocks.
Francium Fr
It was discovered in 1939 AD by Margaret Jerry in France, and it is considered one of the very rare elements in nature. It is sparse in nature, and there are no special applications that use this element, it is only used in biology research.
Radium Ra
This element has an atomic number of 88 and contains 26 radioisotopes; Therefore, it is classified as one of the heaviest alkali metals found on earth, and is distinguished by its pure white color in the soil, but it is oxidized when exposed to air, and during the decomposition of this element and its division into many stages, it produces radon, and when it settles it turns into lead.
Rubidium Rb
The atomic number of rubidium is 37, and it is one of the fragile alkaline metals, and is distinguished by its bright white color that tends to silver, and upon exposure to air it oxidizes very quickly to ignite directly if it is considered one of the highly reactive elements, and it is classified in the group that contains sodium, lithium, and potassium; Because it is similar in properties to these elements in the periodic table.
