Definition of main group element
WebThe group number is an identifier used to describe the column of the standard periodic table in which the element appears. Groups 1-2 termed s-block elements. Groups 1-2 (except hydrogen) and 13-18 are termed main group elements. Groups 3-12 are termed d -block elements. Groups 3-11 are termed transition elements. WebWhat are Main Group Elements? The main group elements are found in the s- and p- blocks, so their electron configurations end in s or p. Group 1 includes elements with one valence electron, group 2 includes elements with two, group 13 includes elements with three valence electrons, and so on until group 18, which includes elements with eight …
