The atoms electrical charge would be 0. As the electrical charge is calculated by taking the number of protons and subtracting it by the number of electrons. In this case the result is 0. (3-3).
Covalent bonds are formed when electrons are shared between elements that are nonmetals. The ammonium ion, NH+4 , would have covalent bonds because both nitrogen and hydrogen are nonmetals. ... So, the bond between this particular hydrogen atom and the central nitrogen is a dative covalent bond.
