Chemistry C4 (1)

group 1- alkali metals 

lithium, sodium, potassium,rubidium,caesium,and fracium

they al have 1 outer electron so they have similar chemical properties 

they all have the following physical properties 

low melting and boiling points 

low density

very soft- can be cut by a knife 

they form ionic compounds they lose their 1 outer electron so easily that sharing it would be out the question so they dont form covalent bonds

you can test for the presence of group 1 metal ions by doing the flame tests 

they are very…
