Types of solids

Which of the following is a characteristic property of solids?

• Particles have translational motion.

• Particles are randomly arranged.

• They are easily compressible.

• Particles are closely packed and have strong attractions.

What is the primary difference between crystalline and amorphous solids?

• Crystalline solids have randomly arranged particles, while amorphous solids have an ordered structure.

• Crystalline solids have a regularly repeating lattice structure, while amorphous solids do not.

• Amorphous solids have stronger intermolecular forces than crystalline solids.

• Crystalline solids are compressible, while amorphous solids are not.

What do the lines between the water molecules represent?

• covalent bonds

• ionic bonds

• intermolecular forces

• intramolecular forces

How do we determine whether the intermolecular force present is dipole-dipole forces or London dispersion forces?

• It depends on the polarity

• It depends on the ionization energy

• It depends on the molar mass

• Depends on the state of matter

Sodium metal is a ​ (a)   solid. A piece of sodium metal is made from sodium ​ (b)   held together by a sea of ​ (c)   .

• metallic
• ions
• electrons
• non-metallic
• atoms
• protons

What type of forces primarily hold molecular solids together?

• Ionic bonds.

• Metallic bonds.

• Covalent bonds.

• Dipole-dipole forces or London Dispersion Forces.

What are ionic solids primarily composed of and what holds them together?

• Molecules held by covalent bonds.

• Nonmetal atoms held by metallic bonds.

• Cations and anions held by ionic bonds.

• Metal cations held by London Dispersion Forces.

Which statement accurately describes covalent network solids?

• They are made of metal cations held by metallic bonds.

• They consist of molecules held together by dipole-dipole forces.

• They are formed from nonmetal atoms held together by covalent bonds in a continuous network.

• They are composed of cations and anions held by ionic bonds.
