How many electrons in the outer shell? | 1 electron in the outer shell |
Properties | they are all shiny, soft, highly reactive metals at standard temperature and pressure |
Reactivity? | readily lose their outermost electron to form cations with charge +1 due to octet rule |
Where are they found? | All the discovered alkali metals occur in nature |
Abundance | in order of abundance, sodium is the most abundant, followed by potassium, lithium, |
other facts about Alkali Metals | They can all be cut easily with a knife due to their softness, exposing a shiny surface that tarnishes rapidly in air due to oxidation. |
