sodium must lose 1 electron, helium is a noble gas it is in group 8 check your Periodic Table, sufide ion must gain 2 electrons
Li- lose 1 e- Br- gain 1 e- Ba- lose 2 e- He- lose/gain 0 e-
Br typically gains one electron to achieve a stable electron configuration, rather than losing electrons.
To achieve noble gas configuration, Bromine must gain one electron. In doing so, it obtains the electron configuration of Krypton. It's new complete electron configuration would be: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6.
Bromine must gain one electron

Every halogen has the capacity to accept one electron from a sodium atom and to thereby achieve a noble gas electron configuration of eight valance electrons. The halogens are fluorine, chlorine, bromine, iodine, and astatine.
The bromine electron configuration is 4s23d104p5.
None - it would have to GAIN one.
Iron has the electron configuration [Ar]3d64s2.
Bromine has seven electrons in its outermost energy level. It can get the stable electron configuration by getting one electron from another atom which makes the -1 charge.

Br typically gains one electron to achieve a stable electron configuration, rather than losing electrons.
Bromine has 7 electrons in its fourth energy level.
1s22s2
bromine has 17 electrons in the valence shell. by gaining one electron it gets the electronic configuration of the next noble gas. hence it gains one electron and forms -1 ion
Bromine want an electron.
Proton = 35 neutron = 46 electron = 35
The noble gas krypton has the same electron configuration as an ion of bromine, Br-.
