What is the kinetic particle theory?

• Matter is a collection of particles in constant, random motion.

• Matter is composed of fixed particles.

• Matter is a collection of particles that do not move.

• Matter is composed of particles that move in a fixed pattern.

Which subatomic particle has no charge?

• Protons

• Electrons

• Neutrons

• Ions

How many electrons can the second energy shell hold?

• 2

• 4

• 6

• 8

What is an example of a compound mentioned in the image?

• Oxygen

• Hydrogen

• Water

• Carbon dioxide

What are the three types of bonds between atoms of a compound?

• Metallic, Ionic, Covalent

• Covalent, Ionic, Hydrogen

• Ionic, Hydrogen, Metallic

• Covalent, Metallic, Hydrogen

What is a covalent bond?

• A bond formed by the transfer of electrons

• A bond formed when two atoms share a pair of electrons

• A bond formed by the attraction between oppositely charged ions

• A bond formed by the sharing of protons

Why are covalent bonds considered strong?

• They are formed by the attraction between ions

• They require a lot of energy to break

• They are formed by the sharing of protons

• They are easily broken

What charge does an atom (ion) have if it loses an electron?

• Negative charge

• Neutral charge

• Positive charge

• No charge

Why is water considered a polar molecule?

• Because of its high boiling point

• Because of the opposite partial charges on opposite ends

• Because it is a solid at room temperature

• Because it contains carbon atoms

What is a characteristic of hydrogen bonds?

• Strong and difficult to break

• Easy to break

• Only occur in metals

• Form between identical atoms
