a negative ion
Nitrogen has 5 electrons in its outer shell, and Bromine has 7 electrons in its outer shell.
Xenon is less reactive. Bromine has 7 electrons in its valency shell and so readily forms a negative ion. Xenon has 8 electrons and so is inert.
A bromine ion with only 26 electrons is not possible. A bromine atom has 35 electrons and it can't loose 9 electrons.

Bromine will gain one electron to become Br-
The element bromine has an atomic number of 35. This means that each atom contains 35 protons, and the requirement for electrical neutrality in an atom means that the atom also contains 35 electrons. A bromide ion contains one more electrons than a bromine atom: 36.
Bromine has 35 electrons in its neutral state, and, as it is a halogen, 36 in its most stable ion. So it would have 4 shells, with 2, 8, 18, and 7 electrons in the neutral state, or 2, 8 ,18 and 8 electrons in its stable ion.
How many electrons does Bromine have
Bromine has 7 electrons. Three bonds with oxygen give sic electrons and the charge gives one. Therefore, bromine has 14 electrons in valence shell in Bromate(V) ion.
If bromine gains one more electron, then it will have 36 electrons total. The only neutral atom with 36 electrons is just the next element on the periodic table, Krypton.
Bromine has 7 electrons in its valency shell and so readily forms a negative ion. Xenon has 8 electrons and so is inert.
a negative ion
Bromine is a non metal element. There are 35 electrons in a single atom.
