Ionic solid harder than molecular solids?
Ionic solids are typically harder than molecular solids because ionic bonds are stronger than intermolecular forces found in molecular solids. The ionic bonds in ionic solids result from the attraction between positively and negatively charged ions, contributing to their higher hardness compared to molecular solids, which are held together by weaker intermolecular forces.
What could you do to determine whether an unknown solid is an ionic compound or a molecular solid?
In the laboratory you could determine if a solid has an ionic bond or a metallic bond by trying to run a current through it. Metal solids have delocalized electrons and conduct electricity well. Ionic solids will not conduct electricity unless dissolved.
What usually has lower melting points than ionic solids?
Molecular solids
What have lower melting points than ionic solids?
Covalent solids typically have lower melting points than ionic solids because the intermolecular forces holding covalent compounds together are weaker than the ionic bonds in ionic solids. Molecular substances, like water and carbon dioxide, also have lower melting points than ionic solids due to the weaker forces between individual molecules.
Is gold and platnium a ionic solid?
No, gold and platinum are not ionic solids. They are metallic elements that form metallic bonds with delocalized electrons. Ionic solids are formed by the electrostatic attraction between positively and negatively charged ions.
What are three characteristic properties of iconic compounds?
If you think to ionic compounds:- dissociation in water- good solubility in water- as solids they are insulators- high melting point

Why the volume solution in conical flask is important in solubility ionic salt in sea water?
The volume solution in conical flask is very important in solubility ionic salt water. This is because it determines its solubility.
What usually has lower melting points than ionic solids?
Molecular solids
Why are ionic liquids used in batteries but ionic compounds are not?
Ionic solids are not dissociated in ions.
What has lower melting points than ionic solids?
Molecular solids
Which type of bond is formed by ionic solids dissolving in water?
Ionic
What three factors affect solubility make sure to include the differences in solids liquids and gases?
Solubility is affected by temperature, pressure, and the nature of the solute and solvent. In solids and liquids, higher temperature often increases solubility, while in gases, higher pressure increases solubility. The nature of the solute and solvent also plays a role, with like dissolving like (polar and ionic substances dissolving in polar solvents, nonpolar in nonpolar, etc.).

Which solid is the strongest-ionic solids metallic solids covalent solids?
Ionic solids tend to be the strongest because they have strong electrostatic forces between positively and negatively charged ions. Metallic solids have a delocalized electron sea that allows for high conductivity but not necessarily the same level of strength as ionic solids. Covalent solids have strong covalent bonds but may not be as strong as ionic solids due to the lack of strong electrostatic interactions.
