Final answer:
False, bromine and krypton have different electron configurations and their highest energy level is not n = 3. The other statements lack context or are also incorrect.
Step-by-step explanation:
The statement concerning bromine and krypton is false. Bromine is a halogen with an electron configuration ending in 4s²2pµ, whereas krypton is a noble gas with a full electron shell, ending in 4p⁶. Thus, they do not have electronic configurations ending in p⁵. Regarding quantum numbers (QN), bromine has n = 4 as its highest energy level, and krypton has n = 4 too, but asserting that both have n = 3 is incorrect. The statement about QN m = +1 is ambiguous without specifying the context, such as which orbital or electron is referred to. Lastly, without specifying which electrons in bromine and krypton are being considered, one cannot conclude that their highest energy electrons have the same spins.
