How many unpaired electrons are there in the following ground-state atoms and ions? If none, enter a zero in the answer box. Sc has ______ unpaired electron(s) Zr4+ has ______ unpaired electrons
Final answer:Scandium (Sc) has one unpaired electron, while Zr⁴⁺ (Zirconium ion) has zero unpaired electrons because all the electrons in its electron configuration are paired.Explanation:The number ofunpaired electronsin an atom or ion can be determined by looking at its electron configuration. ForSc (Scandium), which has an atomic number of 21, the electron configuration is [Ar] 4s² 3d¹. This means Sc has one unpaired electron in its 3d orbital.Zr⁴⁺ (Zirconium), on the other hand, when it loses its four outermost electrons to become an ion, exhibits an electron configuration of [Kr]. Since the electron configuration ends with a noble gas configuration, all electrons in Zr⁴⁺ are paired, meaning it has zero unpaired electrons.Learn more about Unpaired Electrons here:brainly.com/question/31960761#SPJ2...
