📚 Year 10 SQA Chemistry: Quick Vocabulary Memorisation Guide | Year 10 SQA 化学：词汇术语速记指南
In Year 10 SQA Chemistry, mastering the language is half the battle. Without a solid grasp of terminology, even simple questions become confusing. This guide is your companion to fast-track memorisation of the most important chemistry terms you'll encounter. Using mnemonics, word roots, and clever associations, you can turn daunting vocabulary into easy-to-recall building blocks.
在SQA Year 10化学中，掌握术语是成功的一半。没有牢固的术语基础，即使简单的问题也会让人困惑。本指南帮助你快速记忆最重要的化学词汇。利用记忆术、词根和巧妙联想，将令人生畏的词汇变成易于回忆的知识基石。
1. The Power of Terminology | 术语的力量
Chemistry terms often look intimidating, but many are built from ancient roots. For instance, 'hydro-' means water, 'chloros' means greenish-yellow, and 'oxide' refers to oxygen. By decoding these roots, you can guess meanings before you even memorise the definition. This section arms you with the essential prefixes and suffixes that unlock hundreds of words.
化学术语看似令人生畏，但许多源自古老词根。例如，'hydro-'意为水，'chloros'指黄绿色，'oxide'与氧有关。通过解读词根，甚至能在记忆定义前猜到词义。本节将助你掌握解锁数百单词的关键前缀后缀。
Prefix 'mono-' = one, 'di-' = two, 'poly-' = many. Suffix '-ide' signals a simple non-metal anion, like oxide O²⁻ or chloride Cl⁻. '-ate' and '-ite' appear in oxyanions; '-ate' has more oxygen (e.g. sulfate SO₄²⁻) while '-ite' has less (e.g. sulfite SO₃²⁻). Remember: 'I ate more oxygen' for '-ate'.
前缀 'mono-' 代表一，'di-' 代表二，'poly-' 代表多。后缀 '-ide' 表示简单的非金属阴离子，如氧化物的 O²⁻ 或氯化物的 Cl⁻。'-ate' 和 '-ite' 出现在含氧酸根中；'-ate' 含氧较多（如硫酸根 SO₄²⁻），'-ite' 含氧较少（如亚硫酸根 SO₃²⁻）。记忆口诀：'-ate' 我吃了更多氧。
Another clever trick: 'exo-' means out, as in exit (exothermic = heat out). 'endo-' e building blocks, and you will slice through definitions like a hot knife through butter.
另一个巧记法：'exo-' 意为外出，如出口（放热 = 热量放出）。'endo-' 意为进入（吸热 = 热量进入）。训练自己发现这些构词组件，你就能轻而易举地剖解定义。
2. Atomic Structure Terms | 原子结构术语
An atom is the smallest particle of an element that can take part in a chemical reaction. Picture it as the fundamental Lego brick of matter. The memory hook: 'A-tom' sounds like 'a tiny bomb' – not perfectly accurate, but it sticks.
原子是能够参与化学反应的元素最小粒子。把它想象成物质的基本乐高积木。记忆诀窍：'原子'即本原粒子，如同不可切分的米粒。
Protons (p⁺) are positively charged and sit in the nucleus. Link 'Proton = Positive', both start with 'P'. Neutrons (n⁰) are neutral; 'Neutron' has 'neutr' like 'neutral' s whizzing around the nucleus. Think of them as hyperactive negative bees orbiting a hive.
质子(p⁺)带正电，位于原子核内。联想：'质子'的'正'与正电荷对应。中子(n⁰)不带电；'中'就是中性。电子(e⁻)是极小的带负电粒子，绕核飞行。想象它们是一群围着蜂巢飞舞的负电荷蜜蜂。
Atomic number (Z) = number of protons, which defines the element. Say to yourself: 'Z gives me the identity of the atom.' Mass number (A) = protons + neutrons. 'A' stands for 'All the big bits in the nucleus'.
原子序数(Z) = 质子数，决定元素身份。告诉自己：'Z 给我原子的身份证号。' 质量数(A) = 质子数 + 中子数。'A' 代表核内所有大质量粒子。
Isotopes are atoms of the same element with different neutron numbers. 'Iso' means same, 'tope' from Greek for place – they occupy the same position on the periodic table. An ion is a charged particle that forms when an atom gains or loses electrons. Cation (positive) sounds like 'cat' and cats have paws (positive!). Anion (negative) reverses the 'an' to become 'an' onion, which makes you cry – a negative experience.
同位素是同种元素中子数不同的原子。'同位'即周期表中同一位置。离子是原子得失电子后形成的带电粒子。阳离子(正电)像'正电荷'；阴离子(负电)联想到'阴天'，负能量。
3. Periodic Table Trends | 周期表趋势
The periodic table organises elements into periods (horizontal rows) and groups (vertical columns). Picture a 'period' as a sentence in a story that ends and starts a new line – the properties repeat after each row. A 'group' is like a family; members share similar characteristics.
周期表将元素排成周期（横行）和族（纵列）。将'周期'想象成故事中的句子，一行结束新起一行——性质逐行重复。'族'如同一个家族，成员具有相似特性。
Group 1: Alkali metals (Li, Na, K, Rb, Cs, Fr) are soft, highly reactive metals stored in oil. Memory aid: 'Alkali' sounds like 'al-key' – these metals unlock vigorous reactions with water. Group 7: Halogens (F, Cl, Br, I, At) mean 'salt-formers' (Greek 'halos' salt + 'gen' to produce). They are diatomic non-metals with pungent colours. Noble gases (Group 0) have full outer shells and are extremely unreactive – 'noble' like royalty who rarely mix with commoners.
第一族：碱金属（锂、钠、钾、铷、铯、钫）质软、反应性极高，需保存在油中。记忆：'碱'字带'石'，见水就发狂。第七族：卤素（氟、氯、溴、碘、砹）意为'成盐者'，双原子非金属，颜色刺激性。稀有气体（第0族）最外层满电子，极不活泼——'稀有'如孤傲贵族，不与常人往来。
Trends across a period: atomic radius decreases and electronegativity increases. Think 'period = more pull' n energy decreases; the outer electrons are further from the nucleus and easier to remove.
同周期趋势：原子半径递减，电负性递增。想成'周期越往后，原子核越强，把电子拉得更紧'。同族向下：原子半径递增，电离能递减；外层电子离核越远，越容易失去。
4. Bonding and Structure | 键合与结构
Ionic bonding occurs when a metal transfers electrons to a non-metal, forming oppositely charged ions that attract. Think of it as a 'give and take' relationship. Covalent bonding involves sharing electron pairs between non-metals – 'co-' meaning together. Metallic bonding is the attraction between positive metal ions and a sea of delocalised electrons; imagine a lattice of cat-ions floating in a pool of negative charge.
离子键发生在金属向非金属转移电子时，形成正负离子相互吸引。视之为'给予与接受'的关系。共价键涉及非金属之间共用电子对——'共'即共同。金属键是正金属离子与离域电子海之间的吸引力；想象阳离子晶格漂浮在负电荷泳池中。
A molecule is a
