O que faz o sódio reagir de forma tão intensa com a água? O sódio é um metal extremamente mole da família 1 da Tabela Periódica, conhecido como metal alcalino, e possui apenas um elétron na camada de valência. Isso o torna altamente reativo, pois ele tende a perder esse elétron com facilidade. Quando o sódio entra em contato com a água, ocorre uma reação química exotérmica muito rápida, liberando grande quantidade de calor. Nesse processo de oxirredução, o sódio reage com a água formando hidróxi
