The stable ion which is formed of tellurium is Te²⁻ ion.
What are ions?
Ions are those species which are formed by the exchange of electrons from the valence shell of any neutral atom.
Tellurium is an element with the atomic number 52 and electronic configuration of this atom will be shown as:
1s², 2s²2p⁶, 3s²3p⁶3d¹⁰, 4s²4p⁶4d¹⁰, 5s²5p⁴
From the electronic configuration it is clear that, on the outermost shell of tellurium 6 valence electrons are present. And to get stable configuration it will gain 2 electrons from outside and make Te²⁻ ion.
Hence, Te²⁻ is the stable ion of tellurium.
