you don't. you have to find one underground or get another game and trade a Pokemon holding a thunder stone into it
You can either get a Thundestone from Lt.Surge or buy it(with any other known stone at Celadon Market)
You can not buy the thunder stone. Sorry. The way you can find it though, is by mining.
either dig where sparkles are or you can go to the department store in celadon city and buy one on floor 4
you can buy them at the athlete shop in the pokeathlon dome using athlete points.
Usually at the Pokeathlon. You'll need to go to the point exchange corner. They sell random Evolution Stones each day.

Give Pikachu a Thunder stone and it will evolve into a Riachu. But in Pokemon Yellow, the Pikachu will not evolve. You can get thunder stones easy by mining them in Pokemon diamond and pearl but in soul silver and heart gold you need to buy them with athleet points at the athleet shop
