miv72 [106K]
Ernest Rutherford was a famous British physicist who lived and worked in the 19th and the first half of the 20th century. He is now considered to be the father of nuclear physics, given that he was the one responsible for figuring out about the nuclear structure of an atom (proton, electron, neutron) and about the nuclear processes in general. The element rutherfordium (Rf) is named after this scientist. When it comes to his personal life, his parents are both British, however, Ernest was born in New Zealand because his mom and dad before he was born. He worked as a professor in several universities, and was even knighted in 1914. He is a Nobel prize winner, which he won for Chemistry in 1908.

What is the oxidation state, d electron count, and coordination number respectively of the cobalt ion in [CoBr(NH3)4]PO4? What i
Law Incorporation [45]

Answer:

The correct option is: +4, 5, and 5

Explanation:

A coordination complex consists of a central metal atom or ion bonded to ligands by coordinate covalent bonds. The ligands and the central metal together form the coordination sphere.

[CoBr(NH₃)₄]PO₄

Central metal atom - Co

Coordination sphere consists of 1 Br⁻ and 4 NH₃ ligands

<em>Therefore, the coordination number= 5</em>

Let the oxidation state of Co = x

Oxidation state of Br⁻ ligand = (-1)

Oxidation state of NH₃ ligand = 0    

Oxidation state of PO₄³⁻ ligand = -3

∴ x + (-1) × 1 + 0 × 4 + (-3) × 1 = 0

⇒ x = +4

<em>Oxidation state of Co = +4</em>

Electron configuration of Co in ground state: [Ar] 3d⁷ 4s²

Electron configuration of Co in +4 oxidation state: [Ar] 3d⁵ 4s⁰

<em>Therefore, the number of d electrons in cobalt ion = 5</em>
