You can effortlessly find every single detail about the elements from this single Interactive Periodic table.

The most highly reactive element to be observed is. most abundant element overall and the most. On the other hand, reactivity in non-metals increase further right down a period, and further up a group. Let me tell you how this Interactive Periodic Table will help you in your studies.ġ). Caesium, the fifth alkali metal, is the most reactive of all the metals. Free Gift for you: Interactive Periodic Table In this way, the elements of the same group show similar chemical properties and they also have the same number of valence electrons. They are soft and can be cut easily with a kitchen knife.Īlso all the elements of group 1 have one valence electron.Īll the elements of group 18 are chemically inert (that means they do not easily react with other elements).Īnd all the elements of group 18 have a complete octet (that means they have 8 electrons in their outer shell). The elements lying in the same groups show similar chemical properties and they also have same number of valence electrons.Īll the elements of group 1 are highly reactive to water. Plutonium: This highly radioactive element finds use in nuclear weapons and reactors. There are total 18 vertical columns on periodic table. So, the most dangerous elements in practical terms are the heavy metals (lead, mercury) and arsenic.

The most reactive metal is francium, the last alkali metal (and most expensive element).However, francium is an unstable radioactive element, only found in trace amounts. Activity series of some of the more common metals, listed in descending order of reactivity. The most reactive element is fluorine, the first element in the halogen group. It is used to determine the products of single displacement reactions, whereby metal A will replace another metal B in a solution if A is higher in the series. To understand the periodic trends and reactivity of the group 17 elements: the halogens. Groups are the vertical columns on the periodic table. The reactivity series is a series of metals, in order of reactivity from highest to lowest.
