Question: Is Group 1 Or Group 2 More Reactive?

Which element would you expect to be the most reactive in Group 1 in Group 2?

The reactivity of alkali metals increases from the top to the bottom of the group, so lithium (Li) is the least reactive alkali metal and francium (Fr) is the most reactive.

Because alkali metals are so reactive, they are found in nature only in combination with other elements..

Why is Group 1 most reactive?

Alkali metals are among the most reactive metals. This is due in part to their larger atomic radii and low ionization energies. They tend to donate their electrons in reactions and have an oxidation state of +1. … All these characteristics can be attributed to these elements’ large atomic radii and weak metallic bonding.

What is the difference between group 1 and group 2?

The key difference between group 1 and group 2 elements is that all group 1 elements have unpaired electrons in their outermost orbital, whereas group 2 elements have paired electrons in their outermost orbital. … One s orbital can contain only two electrons because the magnetic quantum number of this orbital is 0.

Why is Group 2 less reactive?

The outermost electrons of the alkaline earth metals (group 2) are more difficult to remove than the outer electron of the alkali metals, leading to the group 2 metals being less reactive than those in group 1. These elements easily form compounds in which the metals exhibit an oxidation state of 2+.

What is the least reactive element in Group 2?

The least reactive elements are the noble gases. Within this group, helium is the least reactive element, forming no stable compounds.

Why does reactivity increase down Group 2?

Reactivity. Reactivity of Group II elements increases down the group. This can be explained by the increase in ease at losing two outer electrons as we descend the group. The loss of electrons becomes easier due to the decreasing ionisation energy required.

Which group is least reactive?

Noble gasesNoble gases are nonreactive, nonmetallic elements in group 18 of the periodic table. Noble gases are the least reactive of all elements. That’s because they have eight valence electrons, which fill their outer energy level.

Which group 2 element is most reactive?

alkali metalsThe alkali metals are the most reactive metals. Group 2 consists of the alkaline Earth metals. They are very reactive but less so than the alkali metals.

Is Group 2 highly reactive?

Group 2: Alkaline Earth Metals The alkaline Earth metals include all the elements in group 2 (see Figure below). These metals have just two valence electrons, so they are very reactive, although not quite as reactive as the alkali metals. … They are harder and denser than the alkali metals.

Which element in Group 7a is the most reactive?

FluorineReactions and Compounds of the Halogens. Fluorine is the most reactive element in the periodic table, forming compounds with every other element except helium, neon, and argon.

Which element in group 1 is most reactive?

franciumReactivity of Group 1 Elements The reactivity of alkali metals increases from the top to the bottom of the group, so lithium (Li) is the least reactive alkali metal and francium (Fr) is the most reactive.

What are the properties of Group 2?

For a metal, alkali earth metals tend to have low melting points and low densities. Being a metal, they are obviously good conductors of heat and electricity. The general electronic configuration of Group 2 elements is ns2. Alkali earth metals have the capability to lose the two electrons in their outer shell.
