📚 IGCSE WJEC Chemistry: Mind Map Quick Revision | IGCSE WJEC 化学:思维导图速记
This mind map style revision guide condenses the IGCSE WJEC Chemistry syllabus into easy‑to‑remember visual nodes. Each topic is broken down from a central concept into key branches, helping you link ideas and recall information quickly in exams.
这份思维导图风格的复习指南将 IGCSE WJEC 化学大纲浓缩为易于记忆的可视化节点。每个主题从中心概念分解为关键分支,帮助你联系想法,在考试中快速回忆信息。
1. Atomic Structure & Periodic Table | 原子结构与周期表
Central node: ‘Atom’. Main branches: ‘Subatomic Particles’, ‘Electronic Configuration’, ‘Periodic Table’.
中心节点:“原子”。主要分支:“亚原子粒子”“电子排布”“周期表”。
From ‘Subatomic Particles’, branch to Proton (p⁺, mass 1, charge +1), Neutron (n⁰, mass 1, charge 0), Electron (e⁻, mass negligible, charge –1). Nucleus holds protons & neutrons; electrons orbit in shells.
从“亚原子粒子”分支到质子(p⁺,质量1,电荷+1)、中子(n⁰,质量1,电荷0)、电子(e⁻,质量可忽略,电荷–1)。原子核包含质子和中子;电子在壳层中运行。
Atomic number (Z) = number of protons; Mass number (A) = protons + neutrons. Isotopes share Z but differ in neutrons.
