Q

why does aluminium have the highest MP/ BP?

A

because it has the most electrons in the SODE-

so it has a large electrostatic force.

Q

melting and boiling points of metal ions

A

the more electrons a metal wants to lose,
the higher the ion charge will become
and the electrons there will be in the sea of delocalised electrons.

lower charge + fewer electrons in sode=
lowest electrostatic force, least energy needed.

higher charged ions + more electrons in sode-=
highest electrostatic force, most energy needed
