Electron affinity is that energy released when one electron is added to a gaseous atom of an element. For Mg
Mg(g) + e- -> Mg- (g) ; Energy = 0 kJ/mol
It is different from ionization potential which is the energy required to remove one electron
Mg(g)-> Mg+(g)+2e-
What happens to bromine gas in a sealed tube when it is cooled and later heatedAnswer:When bromine is cooled and then heated in a sealed container, the bromine juice starts evolving in a gaseous state. It then becomes a gas i.e. bromine gas which is red-brown in color
Formula: Br2(L)
