Well, #"rubidium"# is an alkali metal.....

Explanation:

...that forms a #Rb^+# cation....and nitrogen forms a nitride ion....#N^(3-)#

#1/2N_2+3e^(-) rarr N^(3-)#

....and thus we form a #Rb_3N# salt when the ions make music together....and this is probably not something we could put into a bottle.....
