All halogens (group 17) have 7 valence electrons.
Electronic Configuration of Br = 1s22s22p63s23p64s24p5
Number 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
17. The electronic configuration of bromine is 1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 4p5
Bromine wants to have 8 valence electrons to achieve a stable electron configuration, following the octet rule. Bromine has 7 valence electrons in its neutral state, so it typically gains one electron to reach the desired 8 valence electrons.
A neutral atom of fluorine contains 7 valence electrons.
There are 35 electrons in a neutral boron atom arranged in the order 2, 8, 18, 7.
5 valence electrons exist in bromine period, at ground state bromine has 3 valence electrons
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.
A ground state atom of bromine has 28 core electrons. This can be determined by subtracting the number of valence electrons in a neutral bromine atom (7) from the total number of electrons in a bromine atom (35).
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 (Br) has 36 inner electrons. This can be calculated by subtracting the number of valence electrons (7) from the total number of electrons in the neutral atom of bromine (usually 43).
Bromine (Br) has 18 core electrons. This can be determined by subtracting the number of valence electrons (7 in the case of bromine) from the total number of electrons in a neutral atom, which is 35 for bromine.

Bromine has 7 valence electrons available for bonding.
A neutral bromine atom has 35 electrons.
A bromine anion (Br-) contains 8 valence electrons. Bromine is in group 7A of the periodic table and has 7 valence electrons. When it gains an extra electron to form an anion, it now has a total of 8 valence electrons.
nitrogen has 5 valence electrons. carbon has 4 valence electrons.
A bromine anion has 8 valence electrons. This is because bromine, with 7 valence electrons, gains one extra electron when it forms an anion to achieve a full octet and become stable.
