magnesium aluminium zinc iron tin in oreder of reactivity :)
Reactivity series is a list of metals arranged in the order of their decreasing activities.
In the alkali metals column (Group 1), atomic radius increases down the group and reactivity increases. There are more shells preventing the attraction between the positive nucleus and negatively charged outer electron. (All Group 1 elements have 1 electron in their outer shell). Also, because they contain more shells down the group, the distance between the nucleus and electrons is increased. Therefore the electrostatic force is lessened between them. Both of these allow the outer electron to be lost easier to other elements, thus increasing reactivity.

The metals listed are all alkali metals or alkali-earth metals. The periodic trend for these groups is: as you move down the group/family, reactivity increases. The alkali metals will be more reactive than the respective alkali-earth metals.Sodium and lithium are alkali metals, so you can organize them first. Sodium is further down in the family than lithium, so we can say that sodium is the most reactive out of the group, followed by lithium. Then we have barium and radium left. Radium is slightly more reactive than barium due to its position, so it is third and barium is fourth.
I believe it is Beryllium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Sr), Barium (Ba)

Alkaline earth metals are in the 2nd column of the periodic table. They can lose up to 2 electrons without having to pull electrons out of an inner shell, and so alkaline earth metals almost always have a charge of +2

Alkali metals have increasing reactivity going down the group. Francium may not be considered as it is not a stable atom: it is radioactive. The next four are Cesium, Rubidium, Potassium and Sodium in decreasing reactivity order.
YEP! remember In science in order for the Alkali metals and Alkaline earth metals to become stable they must give AWAY electrons. The Earth metals have a Plus 2 charge because they give away 2 electrons on there outer shell!

The rate of corrosion is directly linked to a metal's reactivity. The higher the metal in the series, the more reactive, also more susceptible to corrosion with oxygen and water. aluminum is not easy to corrode. Aluminum quickly reacts with oxygen in the air, and the oxide layer that forms protects the metal underneath from any further reaction.
