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.
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.
Based on the octet rule, bromine requires exactly one electron to fill its valence shell.
Oxygen as 2 core electrons and 6 valence electrons.
2,8,18,7... 28 core electrons 7 valence electrons.
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
Bromine want an electron.
The number of valence electrons is seven.
Silicon has a total of 10 core electrons and 4 valence electrons.
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.
Oxygen as 2 core electrons and 6 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.
