As a result, removing electrons from aluminium requires more energy than removing electrons from sodium, implying that aluminum’s ionisation energy is larger than sodium’s.
As a result, sodium seems more metallic than aluminium.
The metallic character of a metal determines its degree of reactivity.
The reactivity of a metal is measured by its metallic character.
The tendency of a metal to lose electrons determines its properties.
Ionisation energy is used to remedy the problem since metals lose electrons.
Also keep in mind that as you move from left to right in the periodic table, the metallic character decreases.
Final Answer :
Aluminium is less metallic than sodium.
