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.
At least for the Alkali and Alkaline Earth metals, the higher the ionization energy, the less the reactivity.
This is because when a metal reacts, it loses electrons to form ions with stable electron configurations.
When a lot of energy is required for it to lose electrons, it is going to be less likely to react than a metal that easily sheds electrons.
Therefore, the lower the ionization energy, the more reactive a metal will be.

what can you deduce about the relationship between electron affinity and reactivity of non-metals
For metals in the same group, the higher the atomic number the higher the reactivity. This trend is seen as one moves down a metal group.
Group 1 elements have larger atomic radius and greater reactivity than that of the adjacent group 2 elements.
When the atomic radius decrease the ability to loss electrons decrease.
Reactivity of metals describe the order of sequence of metals depending on reactivity. Potassium is at the top of reactivity series.
By there properties: Metals, Non-Metals and Metalliods.
The far left - alkali metals and the far right (not noble metals but next - the Halogens.
in general they become more reactive.
The metals on the left side of the periodic table are considered to be highly reactive to air while in room temperature. The ones on the right side are less reactive and are often used for construction.
Transition metals are located in group 3-12 of the periodic table. The middle of the periodic table.
Reactivity increases the farther down you go in the Periodic Table.
The reactivity increases with increasing numbers of electron shells (energy levels).
By there properties: Metals, Non-Metals and Metalliods.
Reactivity of non-metals increases as you move from left to right on the periodic table, or as group number increases. The most reactive non-metals are found in group 17.
The metals become more reactive as you move down and left.
Reactivity decreases from left to right.Alkali metals on the left are most reactive.While noble gases on the right are least reactive.
The far left - alkali metals and the far right (not noble metals but next - the Halogens.
Maybe there is no pattern...no it fals
in general they become more reactive.
The metals on the left side of the periodic table are considered to be highly reactive to air while in room temperature. The ones on the right side are less reactive and are often used for construction.
The first cloumn in the periodic table has the most reactive elements. The elements decrease in reactivity as you go across the table. in other words alkali metals
