Groups of the periodic Table- Alkali Metals

Question	Answer
What elements are in the Alkali Metals?	lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr)
What Block of the periodic table are they in?	This group lies in the s-block of the periodic table as all alkali metals have their outermost electron in an s-orbital.
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.
