Question

explain chemical reactivity and nature of bonds in alkali Earth metals​

Answer 1

Explanation:

They form ionic bonds by giving up those two electrons to another atom, helping to fill that atom's outer shell. 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

Answer 2

Answer:

(1) The alkali metals and alkaline earth metals are very reactive due to their low ionisation enthalpy. As a result they are always found in combined state.

(2) Alkali metals due to their large atomic raii and low ionisation enthalpy form univalent positive ions $\sf{M^+}$ easily. Therefore, they are more reactive than alkaline earth metals.

(3) Alkaline earth metals form bivalent positive ions $\sf{M^{2+}}$ The reactivity of these metal, increases down the group as the ionisation enthalpy decreases in a group
