It reacts strongly with water, oxygen, and many other substances, while solid sodium is relatively inert and stable. Reactivity: Liquid sodium is much more reactive than solid sodium.9 10 This is because the delocalized electrons in the metallic bonding structure of liquid sodium can move more freely than in the solid state, allowing for greater conductivity. Conductivity: Liquid sodium is a better conductor of electricity and heat than solid sodium.State: The most obvious difference is that solid sodium exists as a solid at room temperature, while liquid sodium exists as a liquid when it is heated above its melting point.Solid sodium and liquid sodium have several differences, both in their physical properties and their behavior. 7 8 How is solid sodium different from liquid sodium? Liquid sodium is commonly used in high-temperature applications, such as in nuclear reactors, where it is used as a coolant due to its excellent thermal conductivity. 6 It has a shiny, silver appearance and is an excellent conductor of electricity and heat. Liquid sodium is a highly reactive and corrosive substance, which can pose safety hazards when handling it. This allows the sodium atoms to move more freely and take on the properties of a liquid. 5 At temperatures above its melting point, the metallic bonding between the sodium atoms weakens, and the kinetic energy of the atoms increases enough to overcome the attractive forces holding them together in the solid form. The melting point of sodium is 97.8 ☌ (208.04 ☏), which is relatively low compared to many other metals. Like most metals, sodium has a relatively low melting point, and it will melt into a liquid state when heated to temperatures above its melting point. Yes, sodium does exist in a liquid state. Overall, the solid state of sodium at room temperature is due to the strong metallic bonding between its atoms, which creates a stable crystal lattice structure. However, if heated to a sufficiently high temperature, the kinetic energy of the atoms can overcome the attractive forces, and the solid will melt into a liquid. 4 This creates a sea of delocalized electrons that allows the sodium atoms to be held together in a solid form.Īt room temperature, the energy of the sodium atoms is not sufficient to overcome the attractive forces between the atoms, which keep them in the solid form. The sodium atoms are held together by metallic bonding, which occurs as a result of the sharing of valence electrons between the atoms. Sodium is a metallic element, and as such, it has a relatively low ionization energy and electronegativity. Sodium exists as a solid at room temperature due to its unique atomic structure and bonding properties. Why does sodium exist as a solid at room temperature?
