non metal reactivity trend on periodic table

Reactivity of metals is based on processes such as the formation of halide compounds with halogens.Trends in the Metallic Behaviour of Elements You can download Metallic and Non-Metallic Character Sheet by clicking on the download button below As we move across the periodic table, there is an increasing tendency to accept electrons (non-metallic) and a decrease in the possibility that an atom would give up one or more electrons(metallic).

Note that there is no clear division between metallic and non-metallic character. It is not found in nature as a free element.įluorine gas reacts explosively with many other elements and compounds and is considered to be one of the most dangerous known substances. However, the element fluorine is the most reactive nonmetal. The noble gases are a special group because of their lack of reactivity. The most reactive nonmetals reside in the upper right portion of the periodic table.

Nonmetals tend to gain electrons in chemical reactions and have a high attraction for electrons within a compound. Learn more about Electronegativity and how it affects Metal and Non-Metallic Character. However, it is so rare that most of its properties have never been observed. It reacts explosively with water and ignites spontaneously in air.įrancium is below caesium in the alkali metal group. The most reactive metal is caesium, which is not found in nature as a free element. This is indicated by their low electronegativities.īy following the trend summary in the figure below, you can see that the most reactive metals would reside in the lower left portion of the periodic table. Within a compound, metal atoms have a relatively low attraction for electrons. Metallic character refers to the level of reactivity of a metal. Metals tend to lose electrons in chemical reactions, as indicated by their low ionization energies.

This is because of the metallic and non-metallic character of the elements. Steel, which is an alloy of iron, is more metallic than iron. But did you ever wonder if one metal is more metallic than the other? Yes. We know that elements can either be metals or non-metals.
