$Hollow \: bones \: are \: also \: called \\ pneumatized \: bones, \: meaning \: they're \: filled \\ with \: space \: for \: air. \: It \\ is \: thought \: that \: this \: structure \\ helps \: with \: oxygen \: intake \: during \\ flight. \: Air \: sacs \: are \: attached \: to \\ the \: hollow \: areas \: in \: a \: bird's \: bones. ... \\ This \: adds \: more \: oxygen \: to \\ the \: blood, \: providing \: a \\ bird \: with \:extra \:energy \:for\: flight.$

Give the nuclear symbol (isotope symbol) for the isotope of bromine, Br, that contains 46 neutrons per atom.

Doss [256]

Bromine has 35 protons, and in this case 46 neutrons, so 35 + 46 = 81
Therefore, the symbol is (subscript 35)(superscript 81) Br.
