Question

Determine the group number of bromine. Provide the number of electrons each of its shells holds and the electron configuration in its valence shell.

Accepted Answer

Bromine is in Group 7A.Shell number 1 contains 2 electrons.Shell number 2 contains 8 electrons.Shell number 3 contains 18 electrons.Shell number 4 contains 7 electrons.The electron configuration of the valence shell of bromine is $$4s^{2}$4p^{5}.$$

Answer

Bromine is in Group 6A.Shell number 1 contains 2 electrons.Shell number 2 contains 8 electrons.Shell number 3 contains 18 electrons.Shell number 4 contains 6 electrons.The electron configuration of the valence shell of bromine is $$4s^{2}$4p^{4}.$$

Answer

Bromine is in Group 7A.Shell number 1 contains 2 electrons.Shell number 2 contains 8 electrons.Shell number 3 contains 18 electrons.Shell number 4 contains 7 electrons.The electron configuration of the valence shell of bromine is $$5s^{2}$5p^{5}.$$
