sodium + chlorine –>

The answers to my last blog, 29th July 2012

The electron arrangement of the sodium ion, Na+ [2,8] is the same as that of the Noble gas neon.

Similarly, the electron arrangement of the chloride ion, Cl- [2,8,8] is like that of argon.

The Noble gases are a group of elements with particularly stable electron arrangements. When the elements sodium and chlorine react forming sodium chloride a lot of energy is given out in a violent exothermic reaction. The product, sodium chloride, is a lot more stable than the reactants, sodium and chlorine. This reaction is shown in the composite photo below:

Sodium metal reacts violently with chlorine gas to make sodium choride

So what is the product formed when lithium reacts with fluorine?
