Answer:
Primary carbocations are most stable, Secondary carbocations are more stable, tertiary carbocations are least stable.
Explanation:
This is due to Asterric hinderance.
The electronic structure of Magnesium is 2,8,2
so in order to form a stable ions, it will lose 2 electrons.
Now, the proton number of Mg is 12, electron number is 10.
It will show positive charge.
Conclusion: Mg will lose 2 electrons to form Mg2+.
Rare earth elements are a series of chemical elements found in the earth's crust and are vital to many of the modern technologies in the world such as computers and networks, advanced transportation and consumer electronics. They help fuel economic growth, maintain high living standards and even save lives. Examples include:
Scandium. Used in television and fluorescent lamps.
Yttrium. Used in cancer treatment drugs, superconductors and camera lenses
Lanthanum. Used to make special optical glasses, telescope lenses and also in petroleum refining.
Neodymium. Used in making some of the strongest permanent magnets, found in most modern vehicles and aircraft.
Because when anything is exposed to air, it come in contact with bacteria which begin to break down the proteins in the beans. But when it’s in a can, it can’t get exposed to bacteria which means it won’t break down.
Hope this sheds some light ♥︎
