<u>Answer:</u> The correct answer is ionization energy.

<u>Explanation:</u>

Ionization energy is defined as the amount of energy required to remove an electron from an isolated gaseous atom to form a positive ion.

Electronegativity is defined as the property of an atom to attract the shared pair of electron towards itself when a bond is being formed.

Electron affinity is defined as the amount of energy released when an electron is added to an isolated gaseous atom to form a negative ion.

Polarity is defined as the separation of electric charge with in the molecule. This leads to the formation of positively charge end and a negatively charged end.

From the above information, the correct answer is ionization energy.

Give the coordination number of the central metal ion in the following complex ions.
melomori [17]

Answer:

a). Coordination no. of [Ni(en)_2(NH_3)_2]^2+ = 6

b). Coordination no. of [Fe(en)(ox)Cl_2]^2- = 6

Explanation:

Coordination number is defined as number of donar atoms bonded to the central atom of the complex ion.

a). Coordination no. of [Ni(en)_2(NH_3)_2]^2+ = 6

en or ethylenediamine is a bidentate ligand.

In bidentate ligand, two atoms directly bonded to the central atom.

NH3 is a unidentate ligand.

So, coordination no.= No. of bidentate ligand x 2 + No. of unidentate ligand

                                = 2\times 2 + 2 = 6

b). Coordination no. of [Fe(en)(ox)Cl_2]^2- = 6

Ethylenediamine (en) is a bidentate ligand.

oxalate ion (ox) is also a bidentate ligand.

Cl is a unidentate ligand

So, coordination no.= No. of bidentate ligand x 2 + No. of unidentate ligand

                                = 2\times 2 + 2 = 6
