What alkaline earth metal is the most reactive?

What alkaline earth metal is the most reactive?

Alkaline earth metals make up group IIA of the periodic table of elements. They all exhibit a single oxidation state, +2, are light, and are reactive, though less so than the alkali metals. Barium and radium are the most reactive and beryllium is the least.

What group does alkaline earth metals bond with?

Group II
You will find the alkaline earth metals right next door in Group II. This is the second most reactive family of elements in the periodic table. Do you know why they are called alkaline? When these compounds are mixed in solutions, they are likely to form solutions with a pH greater than 7.

Which alkaline earth metals form compounds that are covalent rather than ionic?

In fact, most beryllium compounds are molecular (covalent) rather than ionic. This is a consequence of the high charge-to-size ratio of the Be2+ ion, which strongly polarizes bonds to it. Evidence for lower-oxidation-state alkaline-earth metal compounds was controversial for many years.

Which is the least reactive alkaline earth metal?

The least reactive alkaline earth metal is Beryllium (Be). Usually, if we take a look at the reactivity of alkaline earth metals this property tends to increase as we move from the top to the bottom of the group.

When alkaline earth metals form ionic bonds they gain a +2 charge Why do they gain a +2 charge?

All the alkaline earth metals have two electrons in their valence shell, so they lose two electrons to form cations with a 2+ charge.

What kind of bonds do alkaline earth metals have?

The alkaline earth metal takes on a slight positive charge as a result, and the other atom takes on a slightly negative charge. Those opposing charges attract the atoms to form a bond. Beryllium is the exception, because it has a stronger ability to attract other electrons.

Why are alkaline earth metals able to remove both electrons?

The second ionization energy of alkaline earth metals needed for the second electron from the cation will be more than the first ionization energy of the atom, but less than any second ionization of alkali metal. In spite of the high ionization energy, removal of both electrons are feasible because,

How many electrons occur in the outer shell of alkali metals?

The alkaline earths have two electrons in the outer shell. They have smaller atomic radii than the alkali metals. The two valence electrons are not tightly bound to the nucleus, so the alkaline earths readily lose the electrons to form divalent cations.

Which is the lightest of the alkaline earth metals?

The oxides of the alkaline-earth metals are basic (i.e., alkaline, in contrast to acidic). A fairly steady increase in electropositive character is observed in passing from beryllium, the lightest member of the group, to radium, the heaviest.
