Answer:

I>Sb>In>Rb>Xe

Explanation:

Valence electrons are electrons found on the outermost shell of an atom.

In the group of atoms, iodine has seven valence electrons, antimony has five, indium has three, rubidium has one and Xenon has none.

Hence the order stated in the answer

To count the number of valence electrons we look at the electronic configuration and add the electrons form the electronic shell with the highest principal quantum number.

Rb: [Kr] 5s¹ - 1 valence electron

Xe: [Kr] 5s² 4d¹⁰ 5p⁶ - 8 valence electrons

Sb: [Kr] 5s² 4d¹⁰ 5p³ - 5 valence electrons

I:    [Kr] 5s² 4d¹⁰ 5p⁵ - 7 valence electrons

In:  [Kr] 5s² 4d¹⁰ 5p¹ - 3 valence electrons

Rank from most to fewest valence electrons:

Xe > I > Sb > In > Rb
