Group activity is periodic in nature
WebThe elements silicon, germanium, tin and lead are also in group 14. Carbon has some similarities to the metalloid silicon, but silicon cannot be the basis for life like carbon can. It is sometimes called the “king” of the periodic table. Carbon is a non-metal, found in nature as graphite, diamond or fullerenes. WebBy convention, elements are organized in the periodic table, a structure that captures important patterns in their behavior.Devised by Russian chemist Dmitri Mendeleev (1834–1907) in 1869, the table places elements into columns—groups—and rows—periods—that share certain properties.These properties determine an element’s …
