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-
7 electrons in Bromides valence shell
7
5 valence electrons exist in bromine period, at ground state bromine has 3 valence electrons
Bromine want an electron.
The Bromine atom contains: 35 protons, 35 electrons, and 45 neutrons.
A neutral atom of fluorine contains 7 valence electrons.
Bromine is a non metal element. There are 35 electrons in a single atom.
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.
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.
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.
The anion is Br+; bromine has 7 valence electrons.
Bromine must gain one electron
Bromine want an electron.
There are 2 valence electrons in an atom of magnesium. There are 5 valence electrons that are in an atom of phosphorus. There are 4 valence electrons that are in a silicon atom.
nitrogen has 5 valence electrons. carbon has 4 valence electrons.
A barium atom has two valence electrons.
The number of valence electrons is seven.
