Final answer:
The unscrambled words describe the properties of ionic and covalent compounds: Ionic compounds have high melting points and electrical conductivity.
Step-by-step explanation:
The rumbled words pertain to the physical properties of ionic and covalent compounds. Once correctly arranged, these words help describe key characteristics and differences between these two types of chemical compounds. Polarity, Hardness, Electrical conductivity, Melting point.
Ionic compounds are typically hard crystalline solids with high melting points because of the strong electrostatic forces between the oppositely charged ions. These compounds also exhibit high electrical conductivity when dissolved in water or melted, due to the mobility of the ions.
On the other hand, covalent compounds often have lower melting points and hardness, and do not conduct electricity because they consist of neutral molecules held by weaker forces. The polarity of covalent bonds can vary, influencing properties such as solubility and boiling points.
