what is the relationship between melting point and atomic radius

    Melting point trends of atoms is very complex and can not be correlated to
    atomic radius alone.

    There are several reasons for this.

    (1) Across a periodic table row (where atoms become smaller as you go from left to right), the type of interatomic bonding changes from the relatively weak metallic bonds to that of network covalent bonds and then to weak diatomic molecule interactions - thus, because the type of bonding changes, the melting points can not be directly related.

    (2) Down a periodic table group (where atomic radii get larger and one might expect similar intermolecular interactions) the complications happen when access to the d-orbitals are involved and the shielding effect of electrons change. So really, the only group that can be trended is that of the alkali metals and the network covalent group of C (we can not even trend the alkaline earth metals) where as the atoms get larger, the melting points get smaller and this can be related to the inter-nuclei distances, and the compactness of the crystal lattice.

    As you go down the group 1 alkali metals in the periodic table the atomic radius increases their melting point decreases.[ The increase in radius results in much decreased attractive forces between atoms] [4].

    I feel empathy for you i'm trying to do this question for an exam. It's to difficult and their are not enough resources, and then their's the pain of people posting stupid things that won'y help you at all.

    well me nan married me grandad and gave birth to et and then me dad came along on an accident, and then he grew up became a man slag so he had to move out of the country he was in and he then found a professer who took him back in time in a car, he was in the movie 'back to the future'. then he went back to the roman tmes and became g*y as everyone was back then and then he went back to the time he was originally in and then ran round the local g*y bar with a net and now i have lots of daddies, you get me gamu?
