Tin has the atomic number Sn (Z = 50).
(a). Give its electronic structure
(b). Is it one of the transition metals?
(c). Knowing that it loses its electrons in pairs and that the 4d subshell is not affected. What are the possible degrees of oxidation for this element?

Respuesta :

Tin has electron configuration [Kr] 5s²4d¹⁰5p² and it is not a transition element because its outermost orbitals are 5s² 5p². It has oxidation states of +2 and +4.

The electron configuration of tin is [Kr] 5s²4d¹⁰5p². The electronic structure of an atom shows the arrangement of electrons in the atom of an element. The electrons are arranged in sub-shells.

Tin is not a transition metal because it has a completely filled d sub-shell and  its outermost shell consists of ns, np orbitals.

Tin looses its electrons in pairs. Remember that the outermost orbitals are  5s² 5p². This means that tin can have two stable oxidation states, +2 and +4.
