The periodic table is a chart that shows how elements are related to one another. Indium is a transition metal that is also part of the platinum family. The metals in the platinum family are also known as the noble metals. They have this name because they do not react well with other elements and compounds. They appear to be too superior to react with most other substances. In fact, iridium is the most corrosion-resistant metal known.
Precipitation falls as snow when the air temperature is below 2 Â°C. It is a myth that it needs to be below zero to snow. In fact, in this country, the heaviest snow falls tend to occur when the air temperature is between zero and 2 Â°C.
hail: precipitation in the form of balls or irregular lumps of ice (5 mm or more in diameter âanything smaller is considered an âice pelletâ). snow: precipitation composed of white or translucent ice crystals, chiefly in the form of snowflakes. sleet: a mixture of rain and snow. freezing rain: rain that falls when surface temperatures are below freezing â the liquid precipitation freezes when it hits the super-cold surface.
