what is polarisibility and how increase in it is the main factor responsible for the increase in boiling points for noble gases from He to Xe
positive) and anions become more polarizable (larger/more negative) melting points and boiling
points decrease. This is because strong lattices have uniform charge distribution. As ions are
polarized, bonding becomes directional. That is, some interactions strengthen while others weaken.
These weakened interactions are easier to disrupt or melt.
