Question

Write the effective atomic number
of Zn(NH3)4 2+

Answer 1

Answer:

36

Explanation:

EAN = Number of electrons of metal ion + total number of electrons donated by ligands.

OR

EAN = atomic number of (Z) - number of electrons lost by the metal to form ion (X) + number of electrons donated by ligands (Y).

=Z - X + Y

Oxidation state of zinc is +2, therefore X= 2

Four ligands will donate 8 electrons, therefore Y= 8

Atomic number of zinc (Z) = 30

Therefore EAN= Z- X + Y

= 30 - 2 + 8

= 36
