- 1. Category of elements showing dual behaviour, conducting electricity moderately—used in chips and semiconductors.
- 3. Formed by a 1:1 electron transfer between a Group 1 and Group 17 element.
- 5. Physical property determined by mass per unit volume—helps identify unknown substances.
- 8. A molecule held together by the strongest triple covalent bond found in nature.
Down
- 2. An element that forms both a diatomic molecule and a three-atom allotrope essential for life and ozone layer formation.
- 4. Substance made by chemical bonding of elements in fixed proportion.
- 6. A bent-shaped polar molecule due to two lone pairs on its central atom.
- 7. Feature in compounds that stays constant, unlike mixtures that vary in composition.
