Frequently asked questions
- What periodic trends must O Level students know?
- Across a period: nuclear charge increases, atomic radius decreases, metallic character decreases. Down a group: atomic radius increases, reactivity trends vary by group (Group 1 vs Group 17).
- How do I distinguish ionic and covalent bonding?
- Ionic: metal + non-metal, electrons transferred, high melting points, conduct when molten/dissolved. Covalent: non-metals sharing electrons; simple molecules have low melting points, giant covalent structures are very hard.
- What are common O Level bonding mistakes?
- Drawing wrong dot-and-cross diagrams, confusing intermolecular forces with covalent bonds, and not linking structure to properties (e.g. diamond vs graphite).
