Assertion: metal's ionization energy | /r/CapableOf | decrease going down group
Facets:
Source sentences:
text: Since the ionization energy decreases going down a group (or increases going up a group), the increased ability for metals lower in a group to lose electrons makes them more reactive.
text: Ionization energy (the amount of energy required to remove an electron from the atom in its gas phase) decreases down the group.
