Sodium has a low melting point because it has weak metallic bonds, where the positively-charged sodium ions are surrounded by a sea of delocalized electrons. These bonds are relatively weak compared to other types of bonds, leading to a lower melting point temperature for sodium.
Water has a lower melting point because it is soluble in many things. However, naphthalene is not. Without being soluble in a lot solutions the naphthalene has a higher melting point because of how it's formed.
Naphtalene is a totally apolar compound (bicyclo-dibenzene, C10H8, a hydrocarbon) with no hydrogen bonds or other polar groups.
Benzoic acid has one carbonic acid group attached to benzene, which makes it more polar and with intramolacular attraction by hydrogen bonding.
Napthalene is considered to be an aromatic compound and as such is subject to a trigonal planar shape at every bonding site, making the molecule extremely flat. Because the molecule is really flat it is able to more easily pack napthalene molecules together, in other words there is more surface area for the london dispersion forces to hold onto the molecules. Waxes are long fatty acid/fatty alcohol esters and thus also have a lot of surface area for the london forces to interact, however the molecule is anything but flat due to the multiple sp3 tetrahedral carbon-hydrogen bonds so it is less able to "pack".
Sodium oxide has a high melting point because of the strength of its bonds. Due to having strong bonds, they cannot be broken very easily.
it does not have very high melting point 79 - 82 C but boiling point 217 - 218 C
because stearic acid does not give a sharp melting or freezing point as it is rarely pure. Naphthalene is much better

Organic compounds are also covalent compounds what properties would you expect organic compounds to have as a result?
As covalent compounds, organic compounds tend to have relatively low melting and boiling points, be non-conductive of electricity, and have lower solubility in water. They also commonly exhibit isomerism, meaning they can have the same chemical formula but different structural arrangements, leading to a wide range of diverse compounds.
What does diagnosed with low sodium mean?
Being diagnosed with low sodium, also known as hyponatremia, means that the level of sodium in your blood is below the normal range. This can be caused by a variety of factors, including excessive fluid intake, certain medications, or underlying health conditions. It is important to work with a healthcare provider to address the underlying cause and to correct the sodium levels in order to prevent complications.
If you're diagnosed with low sodium in your blood what are the health risks?
Low sodium levels in the blood can lead to symptoms like weakness, confusion, seizures, and, in severe cases, can be life-threatening. It can disrupt the balance of electrolytes in the body and cause complications with nerve and muscle function. It is important to seek medical attention to address the underlying cause and prevent any serious health risks.
Does AT-rich or GC-rich DNA have higher melting temperature?
GC-rich DNA has a higher melting temperature due to stronger hydrogen bonding between guanine and cytosine compared to adenine and thymine. This results in increased stability and a higher melting temperature for GC-rich DNA sequences.
What is the problem when cell expands and bursts because of high sodium ion around outside?
When a cell bursts due to high sodium ions outside, it is likely experiencing osmotic lysis. This occurs when water moves into the cell to balance the high concentration of sodium ions outside, causing the cell to swell and burst. This imbalance can disrupt cell function and lead to cell death.
Is the melting point of sodium higher or lower than rubidium?
The melting point of sodium is lower than rubidium. Sodium has a melting point of 97.8°C, while rubidium has a melting point of 39.3°C.
What it sodium chloride melting point?
The melting point of sodium chloride is 801 0C.
Does sodium sulfide have a high or low melting point?
Sodium sulfide has a high melting point. It melts at around 1180°C (2156°F) due to its strong ionic bonds.
Does sodium have a higher melting point then potassium?
Yes, sodium has a higher melting point than potassium. Sodium has a melting point of 97.8°C while potassium's melting point is much lower at 63.38°C.
Would the melting point of caesium be higher or lower then sodium?
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.
What metal is not malleable?
The elements like sodium and potassium are not malleable. They are soft and have low melting point.
Is sodium a reactive atom?
Yes It's a soft metal, reactive and with a low melting point
What is the difference melting point of sodium iodide and naphthalene?
The melting point of sodium iodide is 651°C, while the melting point of naphthalene is 80.2°C. Sodium iodide has a much higher melting point compared to naphthalene due to stronger ionic bonds present in sodium iodide compared to the weaker van der Waals forces in naphthalene.
What is the melting of sodium chloride?
The melting point of sodium chloride is 801 0C.
Sodium atom melting point?
The melting point of sodium chloride is 801 0C.
What is the melting point of sodium?
The melting point of sodium is 97.79 degrees Celsius (208.02 degrees Fahrenheit).
What is the melting point of sodium cloride?
The melting point of sodium chloride ( NaCl ) is 801 °C, 1074 K, 1474 °F.
