In the linear `I_3^(-)` (triiodide ion), the central iodine atom contains

In a carbonium ion, the central carbon atom is ________.

What is a central atom or ion?

Define central metal atom/ion.

KI combines with I_(2) and forms polyiodide . The number of hybrid orbitals on the central iodine atom is "_____" .

The cationtic part of I_(2)O_(6)(s) has central iodine as :

Describe the molecular shape of I_(3)^(-) . (Hint : Central iodine is of sp^(3) d. - linear)

The ion that has sp ^ 3 d ^ 2 hybridization for the central atom, is :

The ion that has sp ^ 3 d ^ 2 hybridization for the central atom, is :

Explain the terms Central metal atom/ion.
