Definition of main group element
WebAug 13, 2024 · 5.1: Group 1 Metals. Metals show metallic luster, are good conductors of electricity and heat, and are very malleable and ductile. Such properties are characteristic of bulk metals, although the definition of metal atoms or ions is not simple. Metallic elements form basic oxides or hydroxides in the +1 or +2 oxidation states, and become cations ... WebThe group 3 elements are occasionally considered main group elements due to their similarities to the s-block elements. However, they remain d-block elements even when considered to be main group. Groups (columns) in the f-block (between groups 2 and 3) are not numbered. Helium is an s-block element, with its outer (and only) electrons in the ...
