Why is the melting point of sodium chloride is much higher than that of aluminium tetrachloride?
Sodium chloride is an ionic compound whereas AlCl3 is a covalent compound. Ionic compounds have greater melting point due to stronger electrostatic force of attraction.
Why is ionc compounds stronger than covalent compounds?
Ionic compounds have a stronger bond due to the electrostatic attraction between oppositely charged ions, resulting in a lattice structure. Covalent compounds share electrons between atoms, which may not be as strong as the attraction between ions in ionic compounds.
Which of the two has more force of attraction helium or oxygen?
Oxygen has a stronger force of attraction compared to helium because oxygen has a higher atomic number and more protons, resulting in stronger electrostatic forces between its nucleus and electrons.
What two factors determine the size of the electrostatic force of attraction between two objects?
The size of the electrostatic force of attraction between two objects is determined by the magnitude of the charges on the objects and the distance between the objects. The larger the charges and the smaller the distance between the objects, the stronger the electrostatic force of attraction will be.
How does the arrangement of ions in a solid help to explain the high melting points of most ionic compounds?
In an ionic compound, ions are arranged in a regular and repetitive pattern, forming a strong electrostatic attraction between opposite charges. This arrangement requires a lot of energy to break apart, leading to high melting points. The stronger the electrostatic forces between ions, the higher the melting point of the compound.
Is an ionic bond stronger than a covalent?
Covalent bond is made up of electrostatic attraction but ionic bond is made up of weak waalander's force of attraction
Why is an ionic bond stronger than a covalent bond?
Ionic bonds are stronger than covalent bonds because they involve the transfer of electrons from one atom to another, leading to the formation of charged ions that are strongly attracted to each other. This electrostatic attraction between oppositely charged ions results in a strong bond. In contrast, covalent bonds involve the sharing of electrons, which creates a weaker bond compared to the strong attraction in ionic bonds.
How do you know the electrostatic forces are not the cause of gravitational attraction between the earth and moon for example?
Electrostatic forces operate between charged particles, while gravitational attraction acts between masses, with gravity being a universal force that affects all matter regardless of charge. The magnitudes of gravitational forces are vastly stronger than any electrostatic forces at cosmic scales, as evidenced by the behavior of celestial bodies. Additionally, the gravitational attraction between Earth and the Moon is consistent with Newton's law of gravitation, which has no dependence on electric charges, confirming that electrostatic forces are not responsible for this interaction.
Do ionic compounds or covalent compounds have stronger intermolecular forces?
Intermolecular forces are the forces of attraction that exist between molecules in a compound. The stronger the attractions between particles the more difficult it will be to separate them. When substances boil, the particles are completely separated from one another and the attractions between the molecules are completely overcome.
Why there is no repulsion between the protons within nucleus?
There is a stronger force, stronger than the electrostatic force, that keeps nucleons (protons and neutrons) together. It is not enough to hold two protons together if they are alone, but the neutrons provide additional attraction. This force is known as the "strong force".There is a stronger force, stronger than the electrostatic force, that keeps nucleons (protons and neutrons) together.

Why is melting point of sodium fluoride higher than that of sidium iodide?
The higher melting point of sodium fluoride compared to sodium iodide is due to stronger forces of attraction between the ions in the crystal lattice of the fluoride compound. Fluoride ions are smaller and have a higher charge density compared to iodide ions, leading to stronger electrostatic forces between the ions in sodium fluoride, resulting in a higher melting point.
What makes a compound insoluble?
A compound is insoluble when the forces of attraction between its ions are stronger than the forces of attraction between the compound and the solvent molecules. This means that the compound does not readily dissociate into its ions in the solvent, preventing it from dissolving. Common reasons for insolubility include the presence of strong intermolecular forces, such as in ionic compounds with large cations and anions, or the lack of compatible interactions with the solvent molecules.
