Il potassio è un elemento chimico metallico il cui simbolo è K. È il 19° elemento più abbondante nell'universo, di solito si trova sotto forma di sali minerali disciolti negli oceani e nel suolo. È il più abbondante dei tre metalli alcalini, essendo il sodio il secondo e il litio il terzo.
Il potassio è un metallo morbido e argenteo che si corrode facilmente e reagisce vigorosamente con l'acqua. In termini di proprietà fisiche, si presenta come cristalli bianchi o grigi, il suo punto di fusione è 63,38°C (146,1°F) e il punto di ebollizione è 759°C (1400°F). È leggermente più pesante dell'acqua e molto malleabile.
Il potassio è un elemento essenziale per gli esseri viventi, poiché è coinvolto in diversi processi biologici. In particolare è necessario per la contrazione muscolare, la trasmissione degli impulsi nervosi e la regolazione del pH dei fluidi corporei. La carenza di potassio può portare a problemi cardiaci, disturbi muscolari e bassa pressione sanguigna.
Il potassio è utilizzato anche nell'edilizia e nell'industria. È un additivo comune nei fertilizzanti e negli ammendanti perché migliora la qualità e la fertilità delle colture. Viene utilizzato anche in alcuni cosmetici per le sue proprietà idratanti e antinfiammatorie.
