Answer:
○Two electrons in the outer shell and a full outer electron s shell
○Low electron affinities
○Low electronegativities
○Relatively low densities
○Relatively low melting points and boiling points, as far as metals are concerned
○Typically malleable and ductile. Relatively soft and strong.
The elements readily form divalent cations (such as Mg2+and Ca2+).
The alkaline earth metals are very reactive, although less so than the alkali metals. Because of their high reactivity, the alkaline earths are not found free in nature. However, all of these elements do occur naturally. They are common in a wide variety of compounds and minerals.
These elements are shiny and silver-white as pure metals, although they usually appear dull because they react with air to form surface oxide layers.
All the alkaline earths, except for beryllium, form corrosive alkaline hydroxides.
All of the alkaline earths react with halogens to form halides. The halides are ionic crystals, except for beryllium chloride, which is a covalent compound.
<span>Proteins that minimize fluctuations in pH are known as buffers. A buffering agent can be either a weak acid or weak base. Buffering agents are usually added to water to form a buffer solution, which only slightly changes its pH in response to other acids and bases being combined with it, particularly a strong acid or a strong base.</span>
