The sodium atom (NA) and the water (H2O), combine to form NaOH, with a lot of hydrogen gas left over. The reaction releases a lot of heat, and the heat ignites the hydrogen gas. The rest is a boom.

A sodium atom can lose its outer electron. It will still have 11 positive protons but only 10 negative electrons. So, the overall charge is +1. A positive sign is added to the symbol for sodium, Na +.

Japanese researchers' new approach involving copper doping, solves the long-standing issue of stacking faults in sodium batteries.

The sodium atom would be one of billions of trillions of sodium atoms bonded together as a solid. The combination of these substances is a complex reaction between the atoms of the two substances. The ...
