I just want to point out that someone above said “take it for granite” instead of “take it for granted” and no one else noticed. That’s funny.

PS Not trying to give you a hard time, it’s just funny…
PPS I am pretty sure that you can predict the properties of an element from its atomic weight etc, so even if there were only two atoms of Francium on the planet, scientists would know what state it would be in at room temperature. Could be wrong about that. I don’t know what STP or CRC mean, but I did make a wiseass comment so I think I am excused. Or something. Ironically.
