Will the melting point rise if the force of the attraction between positive and negative ions?
Yes, if the force of attraction between positive and negative ions increases, the melting point of the ionic compound will generally rise. Stronger ionic bonds require more energy to break apart, which translates to a higher melting temperature. Conversely, if the ionic attraction weakens, the melting point would decrease.

What type of bonds have high melting point and are soluble in water?
Ionic bonds have high melting points and can be soluble in water. Ionic compounds have strong bonds between positive and negative ions, leading to high melting points, and they can dissolve in water due to the attraction between the ions and the water molecules.
Does Ice melting have a positive or negative enthalpy?
Negtive
What is the type of polar attraction?
Polar attraction refers to the electrostatic forces between polar molecules, which have a positive and a negative end due to the uneven distribution of electrons. This type of attraction occurs because the positive end of one polar molecule is attracted to the negative end of another, leading to intermolecular forces such as dipole-dipole interactions and hydrogen bonding. These attractions play a crucial role in the properties of substances, such as boiling and melting points, solubility, and overall molecular behavior in different states.
What is the strongest type of intermolecular force and responsible for the very high melting points of solid salts?
Ionic bonding is the strongest type of intermolecular force and is responsible for the high melting points of solid salts. In ionic bonding, positive and negative ions are held together by strong electrostatic forces of attraction.
How do diploe-dipole forces affect the melting and boiling points of substances?
Dipole-dipole forces occur between polar molecules and arise from the attraction between the positive end of one dipole and the negative end of another. These intermolecular forces contribute to higher melting and boiling points compared to nonpolar substances, as more energy is required to overcome the attractions between the polar molecules. The strength of dipole-dipole interactions varies with the polarity of the molecules involved, influencing their phase change temperatures. Overall, stronger dipole-dipole interactions lead to elevated melting and boiling points.
Why the melting and boiling points of ionic is higher then atom?
due to the strong electrostatic force of attraction between the positive cations and negative anions in ionic compounds

Solid ionic compounds have very high melting points because they?
have strong electrostatic forces of attraction between the positive and negative ions in their crystal lattice structure. This strong attraction requires a significant amount of energy to overcome, resulting in high melting points.

Which type of substance is most likely to experience an attraction between its particles?
All substances experience attraction between their particles. These vary in type and strength. If there were no forces they would never form liquids or solids. You could say that the strongest bonds are in the substances with the highest melting points.
Why do ionic bonds have a high melting point?
Ionic bonds have a high melting point because they are formed through the attraction between positively and negatively charged ions. This strong electrostatic attraction requires a lot of energy to overcome, hence the high melting point of ionic compounds.
What is the strongest type of intermolecular force and responsible for the very high melting points of solid salts?
Ionic bonding is the strongest type of intermolecular force and is responsible for the high melting points of solid salts. In ionic bonding, positive and negative ions are held together by strong electrostatic forces of attraction.
What is the difference between zircon melting point of 2500 and mercury melting point of negative 39?
2539 degrees
What is the deference between ionic bonds and covalent bonds?
covalent bonds: relatively low melting point, bond is not as strong as ionic, form between two nonmetals, valence electrons are shared between the atoms. ionic: relatively high melting point, stronger bond than covalent, form between a metal and nonmetal, valence electrons are transferred from the metal to the nonmetal, leaving the metal with a positive charge and the nonmetal with a negative charge. these charged particles are called ions. positive ion=cation, negative ion=anion.
How do diploe-dipole forces affect the melting and boiling points of substances?
Dipole-dipole forces occur between polar molecules and arise from the attraction between the positive end of one dipole and the negative end of another.

The strength of dipole-dipole interactions varies with the polarity of the molecules involved, influencing their phase change temperatures. Overall, stronger dipole-dipole interactions lead to elevated melting and boiling points.
When a negative ion and a positive ion bondwhat happens?
When a negative ion (anion) and a positive ion (cation) bond, they form an ionic compound through an electrostatic attraction. The anion donates electrons, while the cation accepts them, leading to a transfer of charge that stabilizes the resulting compound. This bond typically results in the formation of a crystalline structure, characterized by high melting and boiling points. The resulting compound is electrically neutral overall, as the total positive charge from the cations balances the total negative charge from the anions.
