Oxidation state of India
Atoms of India in compounds have an oxidation state of 3, 2, 1.
The oxidation state is the conditional charge of an atom in a compound: the bond in a molecule between atoms is based on the sharing of electrons, thus, if the atom’s charge virtually increases, then the oxidation state is negative (electrons carry a negative charge), if the charge decreases, then the oxidation state is positive.
Oxidation state of an ion In+ = 1

Valence of In+
Atoms of India in compounds have valence III, II, I.
Valence of India is an ability of an atom In to build chemical bounds. The valence is based on electronic configuration of atom: electrons participated in chemical bounds are known as valence electrons. In general the valence is:
The number of possible chemical bounds with other atoms
The valence has no sign.
Quantum numbers In 1+
Quantum numbers are defined by the last electron in configuration, for an ion In these numbers are N = 4, L = 2, Ml = 2, Ms = -½
