Metals and non-metals explained
The periodic table contains over one hundred elements, and most of them are metals.
Read the full explanation
Metals occupy the large block on the left, centre and lower part of the table, including Groups 1, 2 and the transition metals, while non-metals form a much smaller region towards the top right. This matters because the physical and chemical behaviour you meet in later topics, such as conduction, malleability, reaction with acids and formation of positive ions, applies to the majority of elements. For example, iron, copper, sodium and calcium are all metals, whereas oxygen, chlorine and sulfur are non-metals. Recognising that metals dominate the table helps you predict properties and interpret trends rather than learning each element separately.
Your focus
- State that most elements are metals.
- Classify named elements as metals or non-metals using the periodic table.
- Relate the metal majority to typical metallic properties such as conduction and malleability.
Metals and non-metals exam tips
Marking Points
- States that most elements in the periodic table are metals, with non-metals forming a minority.
- Identifies common metals such as sodium, magnesium, iron, copper and zinc from their position or name.
- Links the metal majority to characteristic properties such as electrical conductivity, malleability and shiny appearance.
- Uses the periodic table to distinguish a metal from a non-metal by location rather than by memorising every element.
- Applies the idea that metals generally form positive ions when they react.
Examiner Tips
- 💡When asked to classify an element, quote its position in the periodic table as evidence rather than relying on appearance alone.
- 💡Use the phrase 'the majority of elements are metals' precisely, because 'many' or 'some' weakens a classification answer.
- 💡If a question gives an unfamiliar element, decide metal or non-metal from its position before predicting its properties.
Common Mistakes
- Assuming that about half of all elements are metals; the correct idea is that the large majority are metals.
- Treating hydrogen as a metal because it sits at the top left; hydrogen is a non-metal despite its position.
- Believing that all metals are magnetic or all metals are hard; only some metals are magnetic and hardness varies widely.
