<span>The electron stable state configuration in atoms is best seen in the inert gas configuration.
Inert gas are the most stable since they have their valence electron shell saturated with electrons (the valence shell has the maximum number of electrons it can hold). They need neither donate nor accept electrons.</span>
Pyrotechnic compositions emit light by three basic processes - incandescence (blackbody radiation) atomic emission, and molecular emission.
On the periodic table everything to the right of the line is a non metal
Everything to the left is a metal. So the line crosses to the right is NM to left is M
Evaporation occurs when water molecules at the surface of a pool have enough kinetic energy that the attractive forces holding them to the liquid can be overcome
