Properties of simple molecular compounds

  • Small molecules are compounds made up of molecules that contain just a few atoms covalently bonded together

  • They have low melting and boiling points so covalent compounds are usually liquids or gases at room temperature

  • As the molecules increase in size, the melting and boiling points generally increase

  • Small molecules have poor electrical conductivity

Incredible! SO worth my money, the revision notes have everything I need to know and are so easy to understand. I actually enjoy revising! It makes me feel a lot more confident for my GCSEs in a few months.

Absolutely brilliant, both my girls used it for A levels and GCSE. It's saves on paper copies, also beneficial exam questions ranked from easy to hard. It's removed a lot of stress from the exams.
