Natural beryllium isotopes are: Be-7, Be-9, Be-10.

Beryllium has 4 protons and electrons and a variable number of neutrons, depending on the isotope. For other atomic properties see the links bellow.
The two most common isotopes of beryllium are beryllium-9 and beryllium-10. Beryllium-9 is stable and more abundant, while beryllium-10 is a radioactive isotope with a half-life of about 1.4 million years.
Important beryllium minerals are: beryl, chrisoberyl, phenakite, bertrandite.
The most important minerals of beryllium are: bertrandite, beryl, chrysoberyl, phenakite.
Important beryllium minerals are: beryl, chrisoberyl, bertrandite, phenakite, etc.
The most important isotope of beryllium - 9Be - has 5 neutrons. The neutral atom of beryllium has 4 electrons.
You can tell that the beryllium atom is unstable because beryllium only has 2 valence electrons in its outer shell. An atom becomes stable when it has eight valence electrons, so in the case of beryllium it would have to lose those 2 electrons in its outer shell to become stable. often forming a cation with a 2+ charge.
Because beryllium has some similarities with the other alkaline earth metals; and also the electronic configuration is important.
Beryllium is primarily obtained through mining beryl ore or bertrandite. The ore is processed to extract beryllium using a combination of chemical and physical methods. Beryllium can also be recycled from products that contain this element.
Beryllium reacts with dilute acids to form beryllium salts and release hydrogen gas. However, it is important to handle beryllium with caution as it can be toxic and proper safety precautions should be taken when working with it.
