CGSE Chemistry - Chemical Formulae

This worksheet is an excellent resource for Year 9 Chemistry students to practice identifying elements within a chemical formula and understanding the composition of various chemical compounds. The activity involves analyzing a series of chemical formulas and determining the number of atoms, the number of different elements, and naming the elements present in each formula.

The worksheet contains 15 questions covering a wide range of chemical compounds, from simple molecules like water (H2O) to more complex ones like sugar (C12H22O11). An answer key version of the worksheet is also available, providing detailed solutions for each question.

This exercise is designed to support the understanding of molecular structures, improve chemical literacy, and offer students a hands-on approach to learning how different atoms combine to form compounds. It can be used as a classroom activity, homework assignment, or as a formative assessment to gauge student understanding of chemical formulas.
