Why is the volume of a solid considered definite?

• The particles in a solid are far apart
• The particles in a solid move very quickly
• The particles in a solid are tightly packed
• The particles in a solid exhibit absolutely no movement

Why are ionic solids more brittle than covalent molecular crystals?

• Ionic solids are held together by stronger binding forces.
• Ionic crystals are soft and easy to break.
• Covalent solids are held together by stronger binding forces.
• Covalent crystals contain a greater number of bonds.
