Reactivity of Group 1 Metals: Yes, Mom, I Threw Sodium into Water in Class Today 3....
Which of the following statements about the alkali metals (group 1A) are true? I. Their ionic radii follow the trend Li+ > Na+ > K+ > Rb+ II. Their first ionization energies follow the trend Li+ > Na+ > K+ > Rb+ III. Their reactivity follows the trend Li > Na > K > Rb IV. They have two valence electrons in their neutral atomic form.
Thank you so much for your help :)

Hello, i did a lab where i was given a sample of contaminated water
and must determine the identity of the metals and must percipitate
one out. I was able to determine the identity of metal Y which is
aluminium and metal X which is lithium. Im confused on part 3
though. lithium and alumnium are soluble in almost anything and i
cant use hydroxide or carbonate since lithium is in there, some
help please! I would also like to...
