Answer:
Explanation:
The symbol of beryllium is Be. It is located in the second group on the periodic table.
Beryllium is a divalent cation with a charge of +2.
It is capable of losing 2 electrons in order to be like the noble gas He and this is a more stable configuration.
Answer:
Ion is a charged particle.
A neutral atom contains equal number of positive protons and negative electrons
When an electron is lost or gained the atom becomes a charged particle which is called as an ION.
For example
Na is an atom which contains 11 electrons and 11 protons (= to atomic number)
When Na loses an electron it will have 11 positive proton and 10 negative electron and Thus, Na will become [tex]Na^+[/tex], a charge particle which we call it as sodium ion.
Cl is an atom which contains 17 electrons and 17 protons (= to atomic number)
When Cl loses an electron it will have 17 positive proton and 18 negative electron and Thus, Cl will become [tex]Cl^-[/tex], a charge particle which we call it as chloride ion.
When an ion is positively charged it is called as a cation
When an ion is negatively charged it is called as an anion.
Beryllium forms [tex]Be^{+2}[/tex] cation.we see this in Beryllium chloride [tex]BeCl_2[/tex].
If [tex]BeCl_2[/tex] is present in water it forms Beryllium ions which is in Hydrated form that is [tex]H_2 O[/tex] molecules are present in its ion [tex][Be(H_2 O)_4 ]^{+2}[/tex].
