Beryllium (Be) has a valence of +2. The ion could be written as (Be^2) or (Be+2) …
Beryllium lose electrons (2).
The Beryllium atom , like all atoms has zero(0) charge. However, it is a Group (II) Alkaline Earth Metal and will form the cation Be^2+ . This has a charge of '+2'.
There are four electrons in a Beryllium atom. Hence the mono positive ion has only three electrons. Therefore the electron configuration is 1s2 2s1.
Beryllium has divalent cations Be2+.
A beryllium atom without electrical charge.
Beryllium has 4 protons and electrons and a variable number of neutrons, depending on the isotope. For other atomic properties see the links bellow.
Beryllium the element (Be) has a zero charge. Beryllium the ion (Be^2+) as a plus 2 charge.
Beryllium is an atom / element.
When dissolved in water, beryllium chloride dissolves in water it breaks apart into beryllium and chloride ions. The positive beryllium ion attracts and forms a sort of bond with the slightly positive oxygen atom of a water molecule, forming what is called an ionic complex. A hydrogen ion can then break off of this positively charged complex, resulting in a slightly acidic solution.
Beryllium is element 4, so the "neutral" atom would have 4 protons and 4 electrons. In order to have a "-2" charge, it would need 6 electrons.
The beryllium atom has 4 electrons. As with all other elements, Beryllium atoms are most stable when they have a full outer shell of electrons. Since the neutral electron configuration of the beryllium element atom is 1s2 2s2 (total of 4 electrons) the atom either needs to pick up another six electrons, thereby becoming 1s2 2s2 2p6, or lose two electrons to become 1s2.
