1. What is a compound?
- A. A substance made of only one type of atom
- B. A substance in which atoms of two or more elements are chemically combined
- C. Any mixture of two or more substances
- D. A substance that conducts electricity
2. What happens to electrons during ionic bonding?
- A. They are shared equally between two non-metal atoms
- B. They are transferred from a metal atom to a non-metal atom
- C. They become delocalised across a lattice of atoms
- D. They are destroyed to balance the charges
3. Which type of bonding involves the sharing of pairs of electrons between atoms?
- A. Ionic bonding
- B. Covalent bonding
- C. Metallic bonding
- D. Electrostatic bonding
4. Which statement correctly describes metallic bonding?
- A. Electrons are transferred completely from one metal atom to another
- B. Metal atoms share electrons in fixed pairs with their neighbours
- C. Electrons in the highest occupied energy levels become delocalised and move freely through a lattice of positive ions
- D. Metallic bonding only occurs between a metal and a non-metal
5. A student is told a compound is formed from sodium and chlorine. Based on this, what type of bonding would you predict, and why?
- A. Covalent, because both elements are reactive
- B. Metallic, because sodium is a metal
- C. Ionic, because sodium is a metal and chlorine is a non-metal, so electrons transfer between them
- D. No bonding is possible between these two elements
