Sodium is too reactive too active to be found in nature. When sufficiently
heated, it burns a yellow color. It reacts vigorously with water, so that when
large chunks of it are dropped in it, it often explodes. Most metallic sodium
is used in the manufacture of tetraethyl lead, an antiknock additive for gas.
Other uses are for the manufacture of a variety of organic chemicals, to light
highways, and the reduction of titanium metal. This is also a good electron
source for photoelectric cells and cyclotrons.
