In chemistry, a group (also known as a family) is a column of elements in the periodic table of the chemical elements. There are 18 numbered groups in the periodic table; the 14 f-block columns, between groups 2 and 3, are not numbered. The elements in a group have similar physical or chemical characteristics of the outermost electron shells of their atoms (i.e., the same cor… WebA column in the periodic table is known as a group. Elements in the same group have the same number of valence electrons and react in similar ways. The periodic table is divided into blocks. Blocks are groups of elements that all have their highest energy valence electron in the same subshell. You can also classify elements as metals, non ... add latex to path WebAluminium is positioned in group 3 of the periodic table because it has three valence electrons in its outermost shell. Group 3, also known as the boron group, consists of the elements boron (B), aluminum (Al), gallium (Ga), indium (In), and thallium (Tl). These elements have three valence electrons in their outermost shells, which gives them ...
