Atomic Masses AS Active revision

This is part of a series of ACTIVE REVISION SHEETS for AS Chemistry, designed to help students actively learn by filling in blanks and testing themselves as part of their revision. Each revision sheet consists of alternating A4 question and answer pages. The question pages have gaps and tables to fill in, as well as quick check questions. The answer pages have the same format, but with all the blanks filled in and answers to all questions. The question and answer pages should be printed back to back on A4 or side by side on A3 or A4 (reduced) – in the latter case the sheets should be folded in half to hide the answers. Ideal for self-study or classroom use, students can complete the question pages before looking at the answers to check their learning. Learning outcomes and tick boxes for each outcome are also provided.
This 6 page revision sheet on atomic masses is part of a series primarily aimed at the OCR AS Chemistry specification and relates to the following sections:
Module 2 – Foundations in chemistry
Part 1 – Atoms and reactions
2.1.1 Atomic structure and isotopes

Please review!

Content covered
• Relative masses - comparison of masses to carbon-12
• Calculating relative atomic mass from the masses and abundances of the isotopes
• Mass spectrometry and its use in the above
• Calculating relative molecular and relative formula masses from formulae
• Key definitions of relative atomic mass and relative isotopic mass
