An atom of argon rarely bonds to an atom of another element because an argon atom has

5 0

The answer is (1) 8 valence electrons. Argon, being a noble gas, already possesses a full octet of valence electrons and is, therefore, very, very stable. It has an almost indomitable tendency to retain that octet. That is why it so rarely participates in any sort of bonding.

Explanation:
- All the given compounds have octahedral geometry but the ligand in each are different with the same metal ion.

- Ligands strength order: CN⁻ > NH₃ > F⁻

- The ligand CN will act as a strong field ligand so that the splitting is maximum when compared to NH₃ and F⁻

- If the splitting is more, the energy required for transition is more, and the wavelength is inversely proportional to energy.

- So CN complex will absorb at lower wavelength (yellow color)
