Ionic compounds are generally hard due to the strong electrostatic attraction between the positive and negative ions in the crystal lattice. The arrangement of ions in a regular, repeating pattern contributes to the overall hardness of ionic compounds.

What is one property of covalent compounds?
Covalent compounds share electrons between atoms to form chemical bonds.
Why electrovalent compounds are usually hard crystals yet brittle?
Electrovalent compounds have strong ionic bonds between the cations and anions, which contribute to their hardness. However, these ionic bonds have limited flexibility, making the crystals rigid and prone to shattering when subjected to stress, resulting in brittleness.
Why do ionic copounds tend to be hard solid structures?
Ionic compounds have strong electrostatic forces of attraction between positively and negatively charged ions, which results in a tightly-packed arrangement of ions in a crystal lattice structure. This arrangement makes the ions difficult to move past each other, leading to the hardness of ionic compounds in their solid state.
What do you call a compound that is held together by an ionic bond?
most ionic compounds are salt
Ionic compounds often have higher melting point than metals. Using at least 2 properties of ionic compounds explain why is cookware not made from ionic compounds?
Cookware needs to have good thermal conductivity, while ionic compounds have poor conductivity. Additionally, ionic compounds are brittle and prone to shattering when subjected to mechanical stress, making them unsuitable for cookware that requires durability and resistance to impact.
What are three physical properties of ionic compounds that are associated with ionic bonds and related them to bond strength?
These are melting point, boiling point, hardness.

What do you call compounds that have been formed through ionic bonding?
Ionic compounds.
How does the melting point of ionic compounds compared to that of covalent compounds?
Ionic compounds generally have higher melting and boiling points.

What properties charaterize ionic compounds?
Ionic bonds are very weak, and ionic compounds are very weakly held together chemically.
Are all ionic compounds that dissolve electrolytes?
Not all ionic compounds dissolve into electrolytes. Only ionic compounds that dissociate into ions in solution and conduct electricity are considered electrolytes. Some ionic compounds do not dissolve well in water and consequently do not conduct electricity.
Is PO4 Covalent or ionic?
It is ionic, All the compounds of Sodium are ionic.
How are ionic and covalent compounds different in terms of melting and boiling point and electrical conductivity and hardness and brittleness?
Ionic compounds generally have higher melting and boiling points.
