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)
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.
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.
Bromine must gain one electron
The number of valence electrons is seven.
Based on the octet rule, bromine requires exactly one electron to fill its valence shell.
It needs only 1 more electron since it already has 7 valence electrons.

All halogens (group 17) have 7 valence electrons.Electronic Configuration of Br = 1s22s22p63s23p64s24p5Number of e- in valence shell (outmost s and p-orbital) = 2 + 5 = 7e-
5 valence electrons exist in bromine period, at ground state bromine has 3 valence electrons
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.
Bromine want an electron.
One valence shell
The anion form of bromine, bromide, has eight valence electrons. Bromine normally has seven valence electrons, but gains to to form bromide.
Counting the 4th shell orbitals and their electrons, Bromine has two 4s electrons and five 4p electrons, giving it a total of 7 valence electrons.
Bromine must gain one electron
