  • atomic radius increases

    down the group

  • melting point decreases

    down the group

  • why does melting point decrease down the group

    metallic bonding weakens as the atomic size increases

    due to weakened electrostatic attraction between the nucleus and the delocalised electrons

  • why is the first ionisation energy the lowest

    outermost electrons are held more weakly due to the distance from the nucleus

    and are the most shielded from the nuclear attraction
