掌握 Year 12 OCR 化学中的精确术语是考试成功的基石。本指南将关键术语与实用记忆技巧结合，通过视觉提示、首字母缩略词和逻辑模式将概念串联起来。无论你是在攻克原子结构、能量学还是有机化学，都可以利用这些配对来强化记忆。
1. Atomic Structure and Isotopes | 原子结构与同位素
Atomic number (Z) tells you the number of protons in the nucleus, which defines the element. Mass number (A) is the total of protons and neutrons. Remember: Z is for ‘Zebra’ – each zebra stripe is unique, just like protons define an element.
原子序数（Z）表示原子核中的质子数，它决定了元素的种类。质量数（A）是质子与中子数之和。可记住：Z 像斑马的条纹，独一无二，正如质子决定元素特性。
Isotopes are atoms of the same element with the same number of protons but different numbers of neutrons. Think ‘iso’ meaning same and ‘topos’
