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.

∙ 13y agoAt 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.

Can you show me the periodic table?
By there properties: Metals, Non-Metals and Metalliods.
What are the elements that have the greatest reactivity located in the periodic table?
The far left - alkali metals and the far right (not noble metals but next - the Halogens.
What happens to the reactivity of non metals if you move from left to righton the periodic table?
in general they become more reactive.
How does the the reactivity of metals change when moving from left to right on the periodic table?
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.
Where are transition metals located in the periodic table?
Transition metals are located in group 3-12 of the periodic table. The middle of the periodic table.
What periodic trends of reactivity occur with the alkali metals?
Reactivity increases the farther down you go in the Periodic Table.
What are the rules for reactivity of metals on the periodic table?
The reactivity increases with increasing numbers of electron shells (energy levels).
Can you show me the periodic table?
By there properties: Metals, Non-Metals and Metalliods.
What is the pattern of reactivity observed in the non-metal elements in groups 13-17 of the periodic table?
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.
How does the chemical reactivity of metals change as you move around the periodic table?
The metals become more reactive as you move down and left.
What happens to the reactivity of metals from left or right across the periodic table?
Reactivity decreases from left to right.Alkali metals on the left are most reactive.While noble gases on the right are least reactive.
What are the elements that have the greatest reactivity located in the periodic table?
The far left - alkali metals and the far right (not noble metals but next - the Halogens.
The chemical reactivity of metals tends to increase from left to right across the periodic table.?
Maybe there is no pattern...no it fals
What happens to the reactivity of non metals if you move from left to righton the periodic table?
in general they become more reactive.
How does the the reactivity of metals change when moving from left to right on the periodic table?
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.
What groups of metals is the most active?
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
What are the elements in the periodic table most classified as?
Elements of the periodic table
