Periodic Table
metalloids
-
-
-
-
-
Metalloids such as boron and silicon are the elements that form a diagonal separation between metals and nonmetals in the periodic table. Metalloids have properties somewhat between those of metals and nonmetals, and they often exhibit some of the characteristic properties of each type.
Metals
-
-
-
Elements found in the left two thirds of the periodic table. Most have the following properties - high thermal and electrical conductivities, high malleability and ductility and a metallic luster.
In nature metals are found both in free state and combined state. In free state it is said to be in native state. Most of the other metals are found in nature in the form of compounds. The compounds found inside the earths crust which are rich in a particular metal are called ore. Ores are defined as the naturally occurring mineral from which metals can be extracted cheaply and conveniently.
Nonmetals
-
Elements found in the right one third of the periodic table. They often occur as brittle, powdery solids or gases and have properties generally opposite those of metals. Under normal conditions, they often occur as brittle powdery solids or as gases.
Like metals nonmetals are found both in free and combined state. Some of the non-metals like the noble gases occur in free state because they are least reactive elements. Like metals non-metals are also extracted from their sources for speci
