Question

question true or false 1) the physical properties of ionic compounds are due to their crystalline structure with strong electrostatic forces. 2) the physical properties of metals are due to the attraction between polar ends of each molecule.

Explanation:

1. Ionic compounds have physical properties (like high melting and boiling points) because of the strong electrostatic forces (ionic bonds) in their crystalline structure.
2. The physical properties of metals (such as electrical conductivity, malleability) are due to metallic bonding (sea - of - electrons model) not the attraction between polar ends of molecules (which is relevant for polar covalent molecules like in hydrogen bonding etc.).

Answer:

1. True
2. False
