yes as a duplet electron has to electrons in its outtermost shell.:)
Seven , outer shell electrons or valence electrons increase as you move from left to right on the periodic table not including the transition metals which vary, they start with 1 valence in the alkali earth metals , and finish with 8 valence electrons on the noble gasses (group 18)
Bromine has 7 electrons in it's outer shell. It can hold eight so, it needs 1 more electron. The answer above is is probably the answer expected, however as the the question says outer shell which sometimes is used to refer to the highest principal quantum number, in bromines case 4, the answer could be 25, as the fourth shell can hold 32 electrons.
The valence shell is the outermost shell of the atom. For example, hydrogen (which is located on Period 1) has only one shell and it is its valence shell. Another example, bromine (which is located on Period 4) has four electron shells, and its fourth shell (counting away from the nucleus) is its valence shell containing seven electrons.
Boron can lose 3 electrons from its valence shell that is 2 in 2s & 1 in 2p sub-shell, wheras it cannot gain electron b'coz of its electropositive nature & it has less electron affinity.

Bromine has 7 electrons in its outer shell.
Nitrogen has five electrons in its outer shell and bromine has seven in its outer shell.
Based on the octet rule, bromine requires exactly one electron to fill its valence shell.
Nitrogen has 5 electrons in its outer shell, and Bromine has 7 electrons in its outer shell.
bromine is bigger. bromine has an extra shell of electrons. bromine reacts less vigorously. bromine has a larger amount of protons, neutrons and electrons.
7
seven it has to be
Bromine has 7 electrons in its outer shell and needs to gain one electron to have a full outer shell and become an ion. It will gain this electron from an atom that has one electron in its outer shell such as Lithium or Sodium.
The noble gas krypton has the same electron configuration as an ion of bromine, Br-.
Bromine fills it's valency electrons in the p sub shell. Therefor Br is in the p block.
