D) Kr

Answer 1

The ions that are isoelectronic with Xe are Br- and Kr.

Step-by-step explanation:

The ions that are isoelectronic with Xe are Br- and Kr.

Isoelectronicity refers to having the same number of electrons. Xe has 54 electrons, and both Br- and Kr also have 54 electrons.

Therefore, the answer is option B) Br- and option D) Kr.
