June 2012 Edexcel GCSE Chemistry Unit 1 (Foundation) Mark Scheme

This is the official Edexcel mark scheme for Chemistry Mark Scheme Unit 1 from the June 2012 session. Mark schemes show exactly how each mark is awarded, including acceptable alternative answers, required key terms, and common errors that lose marks. Edexcel mark schemes use notation like "allow," "accept," and "do not credit" to define the boundary between full marks and zero.

This mark scheme corresponds to June-2012-QP---Unit-C1-(F)-Edexcel-Chemistry-GCSE. For maximum revision benefit, attempt the question paper under strict exam conditions first, then use this mark scheme to self-assess. Pay attention to the marking notation: "allow" means an alternative is accepted, "do not credit" means a specific phrasing is rejected even if technically correct, and "ORA" (or reverse argument) means the mark can also be earned with the opposite reasoning.

Edexcel mark schemes reward precise language. For Chemistry, look for keywords the examiner requires — definitions must include specific terms (e.g., "per unit mass," "resultant"), and calculations must show working even if the final answer is correct. Understanding mark scheme conventions helps you write answers that hit every marking point, not just the general idea.

Imprecise or incomplete definitions of chemical terms

“Learn and understand the meaning of key terms such as molecule, isotope, empirical formula.”— 1CH0 Paper 2F, June 2023

How to fix: Learn these definitions precisely from the specification: molecule = a group of atoms joined by covalent bonds; isotope = atoms of the same element with the same number of protons but different numbers of neutrons; empirical formula = the simplest whole-number ratio of atoms; relative formula mass = sum of all relative atomic masses in the formula. For 'isotope', never mix up protons (same) and neutrons (different). Write definitions from memory and cross-check against the syllabus before the exam.
