Predicting and identifying reactions and products

Group 1 contains reactive metals, group 7 contains reactive non-metals and group 0 contains unreactive non-metals. Reactivity increases down group 1 but up group 7. Many metals are transition metals.

Laboratory tests are used to detect and identify gases and ions. Instrumental methods of analysis are faster, more accurate and more sensitive than these simple chemical tests.

Understanding how to approach exam questions helps to boost exam performance. Question types will include multiple choice, structured, mathematical and practical questions.
