Only two electron shells.
Each atom of an isotope of beryllium (or of another element) is different from the atoms of an other isotope. But all the atoms of an isotope are identical.
There are a total of 16 subatomic particles in 2 beryllium atoms. Each beryllium atom contains 4 protons and 4 neutrons in its nucleus, as well as 4 electrons orbiting the nucleus.
You would need to have to phosphate atoms and three berylium. P P P (with their respective dots- so each with 5) and then B B (with two dots) Then you can make arros pointing from the phosphorus to each Berylium atom.
1 mole of the element has 6.023 x 1023 atoms 1 mole = 4 g of helium = 7 g of lithium = 9 g of beryllium = 11 g of boron = 12 g of carbon = 14 g of nitrogen = 16 g of oxygen
In beryllium chloride (BeCl2), we do not draw double bonds between the Be atom and the Cl atoms because beryllium has only two valence electrons and typically forms two single bonds with chlorine atoms. Additionally, beryllium is an electropositive element that does not readily expand its octet or accommodate additional electron pairs. The resulting structure features two single bonds, with each chlorine atom achieving a full octet through the sharing of one electron with beryllium.
An atom of beryllium.
Each atom of an isotope of beryllium (or of another element) is different from the atoms of an other isotope. But all the atoms of an isotope are identical.
The formula for beryllium chloride is BeCl2. It consists of one beryllium atom bonded to two chlorine atoms.

The formula for beryllium chloride is BeCl2. It consists of one beryllium atom and two chloride atoms in a 1:2 ratio.
1 mole of the element has 6.023 x 1023 atoms 1 mole = 4 g of helium = 7 g of lithium = 9 g of beryllium = 11 g of boron = 12 g of carbon = 14 g of nitrogen = 16 g of oxygen
The element beryllium has an atomic number of four. All atoms of this Group 2 metal, regardless of which isotope we might consider, have four protons in their nucleus. And all beryllium atoms have a +4 nuclear charge.
The atomic number of an atom tells you how many protons that atom has. Beryllium's atomic number is 4. That means that, regardless of how many neutrons a given isotope of beryllium may have, it will always have 4 protons.
