WebWe can also assume that it has 8 electrons. So, oxygen has eight positive particles plus eight negative particles. Think of this as 8+ (-8) or 8-8. Eight minus eight equals zero, which is neutral. Basically, a "neutral atom" is an atom that has the same amount of protons as it does electrons. WebTherefore, the element that forms the +3 ion that has the given electron configuration is Cobalt (Co ). Why do we write the 3d sublevel after the 4s sublevel? In the electronic configuration of transition metal we first fill 4s -orbital since the energy of 4s -orbital is less than the 3d -orbital due to screening of nucleus charges. easiest car dealership get financed through

An ion is an atom or molecule with a net electrical charge. The charge of an electron is considered to be negative by convention and this charge is equal and opposite to the charge of a proton, which is considered to be positive by convention. The net charge of an ion is not zero because its total number of electrons is unequal to its total number of protons.
