Knowing the learning objectives is the first step in acing Chemistry. Master the essential concepts and apply them to interesting Chemistry questions confidently. Topical syllabus objective checklists are available here for your self-assessment. These checklists are based on Cambridge O-level Syllabus. Conduct self assessment when you revise. Tick against objectives that you can confidently say ‘I Can Do It’. Revise objectives that you are unsure of. Knowing what you need to know builds confidence in tackling questions.
Work hard. Work smart. All the best.
Self Assessment Checklist - Atomic Structure
|I can do this!|
|a||State the relative charges and approximate relative masses of a proton, a neutron and an electron.|
|b||Describe, with the aid of diagrams, the structure of an atom as containing protons and neutrons (nucleons) in the nucleus and electrons arranged in shells (energy levels).|
|c||Define proton (atomic) number and nucleon (mass) number.|
|d||Interpret and use symbols that represent an element’s nucleon and proton numbers.|
|e||Define the term isotopes.|
