Sr2+ and Br- are isoelectronic. Which has a smaller radius and why?

Sr2+ because it has a greater nuclear charge, which applies a greater force of attraction on the electrons, thereby pulling them closer to the nucleus.

Sr2+ because it has fewer electron shells, therefor have a less distance from the valence electrons to the nucleus.

Br- because it has a greater nuclear charge, which applies a greater force of attraction on the electrons, thereby pulling them closer to the nucleus.

Br- because it has fewer electron shells, therefor have a less distance from the valence electrons to the nucleus.
