Question

Does beryllium have a positive or negative charge?

Answer 1

We need to know that beryllium is a chemical element having the symbol $'Be'$ and having the atomic number four. Usually the charge of an atom will indicate the oxidation state or valence electron of the atom. If the outermost shell is completely filled or half – filled, then the atom becomes highly stable. The most common charges are always equal to the maximum stability of the atom. And the charge is a preserved property of definite subatomic particles.

Complete answer:
The charges of an element can be found out by using the periodic table. The charges of the metal will be positive and the non – metal will be negative. The charge of beryllium is positive. The group $\left( 1 \right)$elements (alkali metals) always carry a $+ 1$ charge and the group$\left( 2 \right)$elements (alkaline earth) contain $+ 2$ charge. The beryllium belongs in the group$\left( 2 \right)$, and it is an alkaline earth metal. The number of gaining and losing electrons depends on the number of groups in the periodic table. And the beryllium has the tendency to lose two electrons and it will attain the electronic configuration of noble gas and it is represented as, $B{e^{2 + }}$.

Note:
We have to know that the charge is a physical property and it is responsible for the force present in an electromagnetic field. And it is a physical property which is present in an element and it will attain by a force when the matter undergoes any reactions like gaining or accepting the electrons. The charges are mainly in two types which are positive charge and negative charge. Same charges will always repel each other and the unlike charges will always attract each other.
