where are the metalloids found in the periodic table
Metalloid The six commonly recognised metalloids are boron, silicon, germanium, arsenic, antimony, and tellurium. Five elements are less frequently so classified: carbon, aluminium, selenium, polonium, and astatine. On a standard periodic table, all eleven are in a diagonal area in the p-block extending from boron at the upper left to astatine at lower right, along the dividing line between metals and nonmetals shown on some periodic tables.
Periodic table The periodic table is a tabular arrangement of the chemical elements, ordered by their atomic number, electron configuration, and recurring chemical properties. This adopted ordering shows periodic trends, such as elements with similar behaviour in the same column. It also shows four rectangular blocks with some approximately similar chemical properties. Generally, within one row (period) the elements are metals on the left, and non-metals on the right. Table rows are called periods and columns are called groups. Six groups have accepted names as well as assigned numbers: for example, group 17 elements are halogens; and group 18 are noble gases.
