Use with a cotton ball. Or, combine the oil with coconut oil (thatâs naturally healing and calming) and gently apply to the contaminated areas. 26) Helps Sooth Inflammation. Massage over the inflamed areas, softly and consistently toward the center, or diffuse and inhale the tea-tree oil directly or indirectly.
Polonium was discovered in 1898 by Polish-French physicist Marie Curie (1867-1934) and her husband, Pierre (1859-1906). They were looking for the source of radioactivity in a naturally occurring ore called pitchblende. Radioactivity is the process by which materials give off energy and change into new materials. Polonium is the heaviest element in the chalcogen family. It is in Group 16 (VIA) on the periodic table. The periodic table is a chart that shows how chemical elements are related to one another. The other chalcogen elements are oxygen, sulfur, selenium, and tellurium.
Thus, its complete electron configuration is 1s2, 2s2 2p6, 3s2 3p6, 4s2 3d10 4p6, 5s2 4d â¦ 10 5p6, 6s2 4f14 5d10 6p4. From this, we see that its highest number shell, which is its valence shell is 6. Thus the valence electron configuration of polonium is 6s2 6p4.ince gallium's atomic number is 31, we know that it has 31 protons and 31 electrons. Thus, its complete electron configuration is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p1. From this, â¦ we see that its highest number shell, which is its valence shell is 4. Thus the valence electron configuration of polonium is 4s2 4p1.
