which of the alkaline earth metal occur in Radioactive form in nature
Answers
Explanation:
All the alkaline earth metals have two electrons in their valence shell, so they lose two electrons to form cations with a 2+ charge. Most of the chemistry has been observed only for the first five members of the group; the chemistry of radium is not well established due to its radioactivity.
In chemical terms, all of the alkaline metals react with the halogens to form ionic alkaline earth metal halides. All the alkaline earth metals except beryllium also react with water to form strongly alkaline hydroxides which should be handled with great care. The heavier alkaline earth metals react more vigorously than the lighter ones.
The alkaline metals have the second-lowest first ionization energies in their respective periods of the periodic table. This is due to their low effective nuclear charges and the ability to attain a full outer shell configuration by losing just two electrons. The second ionization energy of all of the alkaline metals is also somewhat low.
Beryllium is an exception. It does not react with water or steam, and its halides are covalent. All compounds that include beryllium have a covalent bond. Even beryllium fluoride, which is the most ionic beryllium compound, has a low melting point and a low electrical conductivity when melted.
I hope this is help you..
