reactivity of elements

Let us learn about reactivity of elements.

Reactivity of elements table-non metals

The reactivity of non-metals decreases down the series. Fluorine is the most excited or we can say the most reactive non metal where as Phosphorous is the least reactive one. The non metals above in the series can exclude or displace the non-metals below in the series.

Example for reactivity of elements table-non metals: 2KI + Cl₂ → 2KCl + I₂

For metals in a granted period reactivity is determined by the number of electrons that must be transferred to a nonmetal. Those metals with only one outer shell electron will be more reactive than any other metals with two or more electrons.

Reactivity of elements table- metals

The metals are arranged in subsiding (decreasing) order of their reactivity. The most re-active element is at the top level, it is Sodium (Na) The least reactive element is at the bottom level, it is Gold (Au). Hydrogen is a non-metal but it is included in this series as it can form a positive ion by losing an electron. Metals above hydrogen can displace metals beneath (bottom) it from the solutions of their salts.

Example for reactivity of elements table- metals: - Zn + CuSO₄ → ZnSO₄ + Cu

In our next blog we shall learn about deceleration formula I hope the above explanation was useful.Keep reading and leave your comments.
