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.
This is a chemical element. You can find the how many electron in a single atom by using a Periodic Table.
Br has 7 valence e-.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
Bromine has 7 valence electrons, since it is in group 7, and for electron configuration. See on Periodic Table.
7 since it is before Kr, a noble gas. Noble gases have 8 valence electrons
Bromine has 7 valence electrons
Seven, as do the other halogens.
Bromine has 7 valence electrons.

The anion form of bromine, bromide, has eight valence electrons. Bromine normally has seven valence electrons, but gains to to form bromide.
Eight valence electrons.
Based on the octet rule, bromine requires exactly one electron to fill its valence shell.
The anion is Br+; bromine has 7 valence electrons.
Neutral Bromine has three complete rings of electrons. The first ring consists of 2 electrons, the second has 8, the third 18, and the fourth has a maximum capacity of 8 electrons. Bromine only has 7 electrons in it's outer ring, though, so it needs one extra electron to complete it's ring. So to answer your question, it needs ONE more valence electron.
The number of valence electrons is seven.
5 valence electrons exist in bromine period, at ground state bromine has 3 valence electrons

The anion form of bromine, bromide, has eight valence electrons. Bromine normally has seven valence electrons, but gains to to form bromide.
Eight valence electrons.
Bromine must gain one electron
Hydrogen has 1 valence electron. Bromine has 7 valence electrons. When hydrogen and bromine react, the bromine atom 'steals' the hydrogen atom's only electron. The hydrogen atom then has no electrons and the bromine atom has 8 valence electrons. The two atoms are now ions because their number of protons does not equal their number of electrons. The bromine atom is now a bromide anion and the hydrogen atom is now a hydrogen cation (a proton). The two ions remain together, ionicly bonded and together are called hydrogen bromide.
Bromine want an electron.
2,8,18,7... 28 core electrons 7 valence electrons.
Based on the octet rule, bromine requires exactly one electron to fill its valence shell.
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.
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)
