What neutral atom has the same number of electrons as Sc3+? Isoelectronic Species Isoelectronic species are those that have equal electrons. These can be atoms, molecules or ions. They have different physical properties and different chemical properties. Answer and Explanation: Scandium atom has ...
There are no two atoms with the same number of electrons. However, if an atom donates or accepts an electron(s) and turns to either a cation or an anion, the number of electrons in that particle can be the same as many other ions/p...
