Bromine is a chemical element with symbol Br and atomic number 35. It is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly coloured gas. Its properties are thus intermediate between those of chlorine and iodine.
Bromine has Z=35. Ionizing it doesn't change Z, aka the number of protons. Thus, bromine atoms and bromine ions all have 35 protons each. The ions do have one extra electron, but the number of protons can't change without changing the atomic speci...
