Question

Find the EAN of K3Co(F)6 ?​

Answer 1

Answer:

CO2 IS THE CORRET ANSWER

Answer 2

To find,

EAN value of Co in K₃[Co(F)₆]

Solution,

As we know,

EAN (Effective Atomic number) represents the total number of electrons surrounding the nucleus of a metal atom in a metal complex.

Mathematically,

∴EAN = Atomic number - Oxidation number + Number of bonded electrons

Now, For calculating the EAN value of Co in the complex K₃[Co(F)₆], we must first figure out the oxidation number of Co in the complex.

Let the oxidation state of Co in the complex be x.

⇒ x - 6 +3 = 0

⇒ x = 3

The oxidation number of Co = +3

Now,

EAN of Co = Atomic no. of Co - oxidation no. + No. of bonded electrons.

                 = 27 -3 + 12

                 = 36

As a result,

The Effective atomic number (EAN) value of Co in the complex K₃[Co(F)₆] is 36.
