Why is a melted ionic compound a good conductor of electric current but the a solid ionic compound is a poor conductor of electric current?
In a melted ionic compound, the ions are free to move and carry electric charge, allowing the compound to conduct electricity. In a solid ionic compound, the ions are fixed in position and cannot move freely, so they are unable to carry electric charge and conduct electricity effectively.
Is a solid with a melting point of 800 degrees Celsius ionic or molecular?
The melting point of a compound cannot determine the bonding structure. As an example, both diamond and sodium chloride have higher melting points than 800 centigrade but are covalent and ionic compounds respectively.
You are given the melting points of three unknown substances and are asked to predict which one is an ionic compound You would select the compound with the?
Highest melting point. (Note that this does not assure that the remaining compounds are not also ionic.)
Is A compound with a high melting point ionic or covalent?
A compound with a high melting point is more likely to be ionic rather than covalent. Ionic compounds have strong electrostatic forces between oppositely charged ions, resulting in high melting points. Covalent compounds typically have lower melting points because they are held together by weaker intermolecular forces.
What happens when an ionic compound is heated beyond its melting point?
When an ionic compound is heated beyond its melting point, the ionic bonds holding the ions together become weakened due to increased thermal energy. This can cause the ions to break apart, leading to the compound eventually decomposing into its constituent elements.
Why is a melted ionic compound is a good conductor of electric current but a solid ionic compound is a poor conductor of electric current?
Upon melting, the ions are free to move and conduct electricity.

Why would the melting point of a molecular compound generally be lower than an ionic compound?
The ionic bond is stronger.
Why is water lower than the melting point of sodium chloride?
Sodium chloride is a ionic compound. Generally they have high melting points.
Why NaCl has high melting point?
Because it is a ionic compound.
How do you know a compound is ionic or molecular?
An ionic compound is a pure substance that is formed from a metal and a nonmetal. It has a fairly high melting point and is a conductor of electricity when in a molten or aqueous state . A molecular compound, on the other hand, is a pure substance that is formed from nonmetals. It has a fairly low melting point, and cannot conduct electricity regardless of state. Another important difference between the two is that an ionic compound is a crystalline solid at standard ambient temperature and pressure (SATP), whereas a molecular compound can be in a solid, gas or liquid state at SATP.
How do you determine the type of compound ionic or molecular from the melting point such as 1240 degrees C?
If the melting point is at 1240 degrees C then it is most likely an ionic compound, because ionic compounds have their melting points above 800 degrees C while the molecular compounds have their melting point at or below room temperature.
Is low melting pointing a typical property of ionic compound?
No. Ionic compounds are high melting, examples: NaCl 8010C, CaBr2, 7300C; Li2O 15700C)

Which is better solid ionic compound or a melted ionic compound?
"Better" depends on the context. For some purposes solid may be better, for others, melted will be better.
Why is it sodium chloride have the highest melting temperature?
