WebMar 31, 2024 · Non-metallic elements usually have 4-7 elements in its outermost shell. Non-metals have a tendency to gain electrons to complete its octet (duet – in case of Hydrogen). Non-metals with an electronic configuration closest to its stable electronic configuration are the most reactive. This is because it will react quickly to reach a stable octet. WebApr 1, 2016 · Reactivity depends on the nature of other elements in the reaction Nonmetals The halogens and noble gases are nonmetals, although they have their own groups, too. High ionization energy High … A nonmetal is a chemical element deemed to lack a preponderance of metallic properties such as luster, deformability, good thermal and electrical conductivity and the capacity to form a basic (rather than acidic) oxide. Since there is no rigorous definition of a nonmetal, some variation exists among sources as … See more In chemistry, a nonmetal (or non-metal) is a chemical element that generally lacks a predominance of metallic properties; they range from colorless gases (like hydrogen) to shiny solids (like carbon, as graphite). The See more Approaches to classifying nonmetals may involve from as few as two subclasses to up to six or seven.
