Year 11 · Science · Worksheet · $8.99 AUD
A Year 11 chemistry worksheet on atomic structure, isotopes and relative atomic mass. Students find protons, neutrons and electrons in atoms and ions, read isotope notation, calculate relative atomic mass from isotopic abundances for elements such as lithium and magnesium, and work backwards to find percentage abundances for gallium and copper. A teacher answer key is included.
Part of the "Models of the Atom (Particles, Isotopes & Relative Atomic Mass)" sub-unit. Aligned to AC9S11C01, AC9S11C04 (Australian Curriculum v9).
Students will:
• Determine sub-atomic particles in atoms and ions
• Read and write isotope notation
• Calculate relative atomic mass from isotopic abundances
• Calculate percentage abundance from relative atomic mass
A ready-to-teach worksheet, supplied as PDF, editable Word (DOCX) and PowerPoint (PPTX).
