Chemistry Quiz - Bonding (Questions)

Bonding explains why substances have different properties. This GCSE Chemistry quiz covers ionic, covalent and metallic bonding, and how electron arrangement and structure affect melting point and conductivity.

Fascinating Fact:

Ionic bonding forms between metals and non-metals by electron transfer. Positive and negative ions attract in all directions in a giant ionic lattice.

In GCSE Chemistry, bonding links what particles do to what materials are like. You compare electron transfer, electron sharing, and delocalised electrons, then use structure to explain melting point, strength and electrical conductivity.

Key Terms

  • Covalent bond: A strong bond formed when atoms share a pair of electrons.
  • Metallic bonding: The attraction between positive metal ions and a sea of delocalised electrons.
  • Lattice: A regular, repeating arrangement of particles, such as ions in an ionic compound or atoms in a giant structure.

Frequently Asked Questions (Click to see answers)

What is ionic bonding in GCSE Chemistry?

Ionic bonding is the attraction between oppositely charged ions formed when electrons move from a metal atom to a non-metal atom. The ions arrange in a repeating structure held by strong electrostatic forces.

Why do ionic compounds conduct electricity when molten or dissolved?

Ionic compounds conduct when molten or dissolved because the ions can move and carry charge. In a solid ionic lattice, the ions are fixed in place so they cannot carry current.

What is the difference between simple molecular and giant covalent structures?

Simple molecular substances have small molecules with weak forces between them, so they often melt or boil at lower temperatures. Giant covalent structures are large networks of atoms with many strong covalent bonds, so they are usually very high melting.

[x] Covalent
[ ] Hydrogen
[ ] Ionic
[ ] Metallic

10. Graphite is a substance made of carbon atoms only, as is diamond. However, the two substances are very different. Why?
[ ] The atoms in diamond are arranged in layers and the atoms in graphite are arranged in a giant covalent structure
[x] The atoms in diamond are arranged in a giant covalent lattice and the atoms in graphite are arranged in layers
[ ] The atoms in diamond are arranged in a giant covalent structure and the atoms in graphite are arranged at random
[ ] The atoms in diamond are arranged at random and the atoms in graphite are arranged in layers
The atoms in graphite are in layers. The bonding between the layers is weak and because of this they can slide over each other, making the substance very soft and slippery - it is a good lubricant e.g. for things like zip fasteners
