WebJul 10, 2015 · From the physicists' "electron sea" point of view of metal bonding, the higher the ionic charge the metal atom can support, the higher the element's melting and boiling points. This explains why group 1 metals such as sodium have quite low melting/boiling points since the metal would be composed of electrons delocalized in a $\ce{M}^+$ lattice.

WebNov 30, 2024 · With the Clausius-Clapeyron equation is possible to determine the boiling point of any substance at a given pressure. Let's take a closer look: \small ln\left (\cfrac {P_1} {P_2}\right) = \cfrac {-\Delta H} {R} \ \times \left (\cfrac {1} {T_1} - \cfrac {1} {T_2}\right) ln(P 2P 1) = R−ΔH × (T 11 − T 21) where: P_1 P 1 — Pressure at state 1; P_2 P 2 WebExplain how the conductivity of electricity and the high melting points of metals are explained by metallic bonding. Delocalized electrons can move through the solid to conduct an electric current. The number of delocalized electrons and the strength of a metallic bond determine the melting point.
WebAug 12, 2024 · If the number of unpaired electrons increases then metallic bond becomes stronger and hence the metal elements show high melting and boiling point. Since Zn, Cd and Hg have no unpaired...
