![]() These metals include lithium, sodium, potassium, rubidium, cesium, and francium. The alkali metals are the family of elements that contain the most reactive elements. To put it simply, the bigger the size of atoms, the bigger the reactivity. They are easy to remove, so the atoms readily form chemical bonds. Move down a column or group of the period table, and the size of the atomic radius increases.įor metals, this means the outermost electrons becomes farther away from the positively-charged nucleus. On the other end of the spectrum, we have highly reactive metals like cesium and francium, who readily form bonds with electronegative atoms. For example, an element like fluorine, who is highly electronegative, has an extremely high attraction for bonding electrons. ![]() Reactivity is a measure of how likely a chemical species is to participate in a chemical reaction to form chemical bonds. Scientists also use trends in the periodic table to predict reactivity of metals and non-metals. The series is basically a chart listing elements according to how readily the metals displace H2 in reactions. The metal activity series can help scientists predict which metal will be the most reactive and to compare reactivity of different metals. That makes them more reactive than other metals. They are ultra-keen to pass on this unwanted passenger to another element via bonding. But the alkali metals have only one electron on their outer shell. To achieve that feat, metals tend to shed electrons. Or in other words, they strive to have a full outer electron shell. Generally speaking, elements strive to be chemically stable. ![]() Some of these metals can produce explosions when dropped in water. Did you know that some metals are so reactive that they explode on contact with water? Certain metals like potassium, sodium, lithium, rubidium, and more, are so reactive, that they oxidize (or tarnish) instantly when exposed to air.
