I’m doing chemistry revision on the group one elements. My teachers taught me that the reactivity increases further down the group. When I looked on the internet it states that Potassium is more reactive than Sodium. I don’t understand why or am I just being dumb?

sometimes google goes wrong

now it is showing potassium is more reactive but actually it is Not sodium is more like salts have less sodium bcz it is harmful so thats why sodium is stored in kerosene like if u inhale sodium your nose will bleed it is reactive under water and air .

hope it helps

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
