A halogen is located in group 17 of the Periodic Table, so the electron configuration for the valance electron would be ns2np5 (n=energy level). So all halogens have 7 valance electrons.

How many valence electrons are present in the atom Nb?
There are 5 valence electrons present in the atom Nb (niobium), as it is located in group 5 of the periodic table.
How many total p electrons does an atom of Sn have?
An atom of Sn (Tin) has 4 valence electrons in the 5th shell, so it has 4 p electrons.
How many valence electrons does HBr have?
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.
