Mgo melts at a much higher temperature than naf. MgO melts at a much higher temperature (2,852C) than NaF (993C). . Jul 12, 2020 · Why does MgO melt at a much higher temperature than NaF? Both are ionic solids. Because MgO (Mg2+ and O2−) has ions with greater charges than NaF (Na+ and F−), it takes more energy to break the bonds in MgO resulting in a higher melting point. The electrostatic attractive force between ions with a +2 and -2 charge is much greater compared to the electrostatic force between ions with a +1 and -1 charge. Why does Magnesium Oxide have a higher melting point than Sodium Chloride? Both Magnesium Oxide and Sodium Chloride exist as a giant ionic lattices where each oppositely charged ion is held in place by a strong electrostatic attractions. - The higher melting point of MgO can be attributed to the stronger electrostatic forces due to the bivalent nature of the ions compared to the univalent nature in NaF. Feb 24, 2023 · In LaTeX format: The melting point of MgO is higher than that of NaF because the ionic bond in MgO is stronger due to the greater product of the charges of its ions (Mg 2 + and O 2 −) compared to the ions in NaF (Na + and F −). Both MgO and NaF are ionic solids. The attractive forces holding the ions together are ionic. - The melting point of NaF is around 990°C, while the melting point of MgO is significantly higher at about 2640°C. For example, MgO and NaF both have ionic bonds, but the stronger attractions in MgO due to higher charges lead to a higher melting point. This is similar to comparing MgCl₂ and NaCl, where MgCl₂ retains its solid form at a much higher temperature due to its stronger ionic bonds. Use the Born-Lande equation to help explain your answer (there may be more than one reason). Question: Why is the melting point of MgO much higher than NaF, when they both have the same crystal structure and very close molecular weights. ogherfhz qcmvw jttkq tmn wkeina taeoejl mtpb fepxf zkpbdvv aceh
