Bonding
15 review questions with answers for Bonding. Read them here, or play the set as a class game on the projector. Free to host, and students join with a code.
Type of bonding between a metal and a non-metal?
- IonicRight answer
- Covalent
- Metallic
- Hydrogen
What this set covers
Ionic, covalent and metallic bonding, and how each explains melting points and conductivity. Examples include the ions Na⁺ and O²⁻, the formula MgCl₂, methane, double bonds in O₂, and the carbon forms diamond and graphite.
- Common mix-up
- Students often mix up breaking covalent bonds with overcoming intermolecular forces: simple molecular substances boil at low temperatures because only the weak forces between molecules need to be overcome.
- Review tip
- Make a three-row table for ionic, simple molecular and metallic substances, then fill in the particles present, melting point and whether they conduct, and justify each entry.

Play it as a class game
Play this set opens it in splycr, where you can host it for your class straight away. Hosting needs no account: put the room code on the projector, and students join from a phone with the code and their first name. Each question plays as multiple choice, and the three wrong options were written for that question.
