IODINE

Iodine has atomic number 53 with a symbol I, is a solid nonmetallic element of the Halogen family. Group VIIA in the periodic table, a group that includes Flourine, Chlorine, and Bromine. At room temperature iodine is a lustrous, blue black, crystalline solid of atomic weight 126.9045. Iodine is the least water soluble halogen, but it dissolves readily in alcohol, chloroform, carbon tetrachloride, and benzene. Iodine is poisonous, but as a trace element it is essential to plant and animal growth. In higher mammals it is concentrated in the Thyroid gland and is involved in the synthesis of thyroxine and other biochemicals that grown metabolic activities. Besides affecting growth, iodine deficiency can also cause goiter, so iodine salts are added to table salts in regions where iodine levels are low.

The Miracle of Planet

The Milk Way is the giant galaxy system that contains of our solar system. Pluto the farthest planet from sun, only stone and very cold air, the surface temperature reach to – 238oC, because of this very cold temperature the surface become a block of ice, a dead ice. The Milky Way Pluto Neptune, one another frozen planet with the surface temperature reach of -218oC, the atmosphere contain helium, hydrogen and methane are poisonous for life being. High methane contain make this atmosphere have blue color. The environment with great storm with speed of 2000 km/hour. Neptune Uranus the dead planet, the mostly planet composed from stone and ice. Need 84 years of Earth for Uranus to circle the sun, atmosphere with hydrogen, helium and methane very poisonous for live. Uranus Saturn’s is the second biggest planet of the sun, with the ring circle them, this ring contain of gas, stone and ice, the whole planet composed by gas, 75% hydrogen and 25% helium. The density of this
