in the valence shell of bromide 7 electrons are present. So the valency of bromide is 1
The anion form of bromine, bromide, has eight valence electrons. Bromine normally has seven valence electrons, but gains to to form bromide.
The group numbers tell the number of valence electrons. Without looking on the group number you can also tell the number of valence electrons by looking at the highest energy level in the electronic configuration.
Take the atomic number then subtract the amount of valence electrons. Example: Number of non valence (inner) electrons in Sulfur: 16 (atomic number) - 6 (valence electrons) = 10 (valence or inner electrons)
Hydrogen has a valence of 1.
-1 for bromine in bromide
The anion form of bromine, bromide, has eight valence electrons. Bromine normally has seven valence electrons, but gains to to form bromide.
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.
its a valence number which is and above
the number of valence electrons is the number group on the table its on
Take the atomic number then subtract the amount of valence electrons. Example: Number of non valence (inner) electrons in Sulfur: 16 (atomic number) - 6 (valence electrons) = 10 (valence or inner electrons)

Two valence electrons.
Hydrogen has a valence of 1.
The expected number of valence electrons for a group 3 A element is 5 number of valence electrons.
2 is the standard number of valence electrons
It has 4 valence electrons and a valence electron potential of 95.2
