Final answer:
Indium is a metal in the same period as boron, while beryllium is not.
Step-by-step explanation:
Indium is a metal in the same period as boron. In the periodic table, elements in the same period have the same number of electron shells. Boron is in period 2, so the other element in period 2 is
indium. Beryllium, on the other hand, is in period 2 but in group 2, so it is not in the same period as boron.
