True or False: Simple covalent substances have low melting points because the covalent bonds within the molecules are weak and easy to break.

True or False: In an alloy, the presence of different-sized atoms distorts the regular lattice, making it easier for the layers of metal ions to slide over each other.

What term describes the relative ability of an atom to attract a shared pair of electrons within a covalent bond?

True or False: When water boils, the covalent bonds between oxygen and hydrogen atoms within the water molecules are broken.

True or False: Ionic compounds are typically brittle because shifting the layers of the lattice can bring ions of the same charge into contact, leading to strong repulsion.
