Bromine is a member of the halogen family of elements. Its companions include fluorine, chlorine, and iodine. Like the other halogens, bromine has seven electrons in its outer shell and is very reactive. You will find bromine in many salt compounds with alkali metals. Sodium bromide is a compound found in seawater. As with all reactive elements, bromine is never found alone in nature. It is always a part of a compound with other elements. Source: Chem4kids
Iodine's electron configuration is 2, 8, 18, 18, 7; bromine's is 2, 8, 18, 7. At the simplest level of modelling there is one more electron shell occupying space in an iodine atom than in one of bromine.
Sodium, i believe has 3 shells.
Uranium has 92 electrons, which means it has 7 electron shells.
2,8,18,7... 28 core electrons 7 valence electrons.

Bromine has 4 energy shells.
Bromine (Br) has 35 electrons in total. It has 7 valence electrons (outermost shell) and 28 core electrons (inner electron shells).
Iodine's electron configuration is 2, 8, 18, 18, 7; bromine's is 2, 8, 18, 7. At the simplest level of modelling there is one more electron shell occupying space in an iodine atom than in one of bromine.
Bromine's atomic radii is larger than that of chlorine.
Bromine typically has 7 electrons in its outer shell.
Bromine has the larger ionic radius than fluorine. This is because when moving down a group on the periodic table, atomic size increases due to the addition of more electron shells. Bromine, being below fluorine on the periodic table, has more electron shells and thus a larger ionic radius.
Magnesium has three electron shells. The electron configuration is 2,8,2
Polonium has 6 electron shells.
Sodium, i believe has 3 shells.
Chlorine is in 3rd period and 17th group bromine is in 4th period and 17th group. The number of shells present in an atom is equal to the period no. In which it is present. So, chlorine has 3 shells while bromine has 4 shells. And atomis size is the distance between centre of nucleus and outermost shell. So, bromine atom is larger than bromine atom..
Bromine tends to gain one electron to achieve a stable electron configuration, making it an electron acceptor (accepts one electron).
