The melting point of caesium will be greater because of random, temporary dipoles caused by moving electrons called London dispersion forces. The bigger the electron cloud of an atom, the greater chance there is for a temporary dipole to exist. Caesium atoms, with LDF happening more frequently, will be harder to drive apart, and the melting point is increased.
Aluminum oxide has a higher melting point than sodium chloride. Aluminum oxide has a melting point of around 2072°C, while sodium chloride has a melting point of 801°C.
Sodium Oxide (SOX) Melting point: 1132 °C, 2070 °F Boiling point: 1950 °C, 3542 °F
Sodium Chloride has a higher melting point because at room temperature it is a solid but Ethyl alcohol has already melted, as it is liquid.
The melting point increases from sodium to aluminum because as you move across the periodic table from left to right, the atomic size decreases while the nuclear charge increases. This results in stronger metallic bonding, requiring more energy to overcome and leading to higher melting points. Additionally, aluminum forms metallic bonds that are stronger than those of sodium due to its higher charge and smaller size.
Aluminum has a higher melting temperature than sodium because aluminum atoms are held together by stronger metallic bonds compared to the weaker metallic bonds between sodium atoms. This results in a higher energy requirement to break these bonds and melt aluminum. Sodium's lower melting temperature is due to its larger atomic size and weaker metallic bonding.
The melting point of cesium is lower than that of sodium. Cesium has a melting point of 28.4°C, while sodium has a melting point of 97.8°C.
Caesium melts at 28.44oC, which is the lowest known melting point for any metallic element other than mercury. Certain radioactive elements might have lower melting points if it were possible to collect a large enough quantity of them to actually determine the melting point. For example, the melting point of francium is expected to be lower than that of caesium (but still higher than that of mercury). Also, some alloys melt at low temperatures. A eutectic alloy of sodium and potassium melts at around -12oC, still higher than mercury, but below caesium (and well below either sodium or potassium alone as well).
