What is the symbol beryllium is most likely to form ? and what kind of ion is it ?

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.

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 , 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 , 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 cation.we see this in Beryllium chloride .

If is present in water it forms Beryllium ions which is in Hydrated form that is molecules are present  in its ion .

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
