📚 Periodic Table to Colour: Finished | 周期表着色：完成版

In KS3 CIE Science, colouring a periodic table is more than a classroom display task. It helps you build a visual memory of element families, metal and non-metal positions, and the staircase line that separates them. This finished guide gives you a clear method to complete your own colour-coded periodic table and use it for revision.

在KS3 CIE科学课程中，给元素周期表着色不只是课堂展示任务。它能帮助你建立对元素族、金属和非金属位置以及分隔它们的阶梯线的视觉记忆。这份完成指南给你一个清晰的方法，让你完成自己的颜色编码周期表，并用于复习。

1. Why Colour the Periodic Table? | 为什么给周期表着色？

Colour coding turns a large, dense table into a map you can read quickly. Instead of checking every symbol, you can see at a glance whether an element is an alkali metal, a halogen or a noble gas. This supports the CIE KS3 skill of identifying patterns in data.

颜色编码把一张大而密集的表格变成一张可以快速阅读的地图。你不必逐个查看符号，就能一眼看出某个元素是碱金属、卤素还是稀有气体。这有助于培养CIE KS3中识别数据模式的技能。

A finished coloured table also saves revision time. When you practise exam questions, the colours act as memory cues for group numbers and typical properties such as reactivity or state at room temperature.

一张完成着色的周期表还能节省复习时间。当你练习考试题目时，颜色会作为记忆线索，帮助你回忆族序数和典型性质，例如反应性或室温下的状态。

2. What You Need Before You Start | 开始前需要准备什么

Use a printed periodic table with clear squares for each element. If your teacher has given you a blank outline, check that the atomic number and symbol are visible before you begin shading. Coloured pencils or fine-tip highlighters work best because they do not cover the labels.

使用一张每个元素方格清晰的打印版周期表。如果老师给了你一张空白轮廓图，在开始涂色前检查原子序数和元素符号是否清晰可见。彩色铅笔或细头荧光笔效果最好，因为它们不会遮住标签。

Keep a ruler and a spare sheet of paper to test colours. Avoid dark blue or black for large regions because symbols may become difficult to read. A light hand with pencils gives a neat finished look.

准备一把尺子和一张草稿纸来试色。避免在大区域使用深蓝色或黑色，因为符号可能变得难以辨认。用铅笔轻轻涂色可以呈现整洁的成品效果。

3. Understanding Groups and Periods | 理解族和周期

Groups are the vertical columns of the periodic table. In the modern numbering system used by CIE, groups run from 1 on the left to 18 on the right. Some older tables label the final column as Group 0, so check the key your school uses.

族是周期表中竖直的列。在CIE使用的现代编号系统中，族从左边的第1族到右边的第18族。一些旧表将最后一列标为第0族，因此要检查你学校使用的图例。

Periods are the horizontal rows numbered 1 to 7. Elements in the same period have the same number of electron shells. For example, sodium Na and chlorine Cl are both in period 3, but they belong to different groups.

周期是水平行，编号从1到7。同一周期的元素具有相同的电子层数。例如，钠Na和氯Cl都在第3周期，但它们属于不同的族。

4. Colour Coding by Chemical Family | 按化学族进行颜色编码

The most common KS3 key colours the major chemical families. Group 1 alkali metals, Group 2 alkaline earth metals, Groups 3–12 transition metals, Group 17 halogens and Group 18 noble gases each get a distinct colour. This makes the table easy to recall in exams.

最常见的KS3图例为主要化学族着色。第1族碱金属、第2族碱土金属、第3–12族过渡金属、第17族卤素和第18族稀有气体分别使用不同颜色。这使得周期表在考试中更容易回忆。

If you follow this scheme, hydrogen usually stays with Group 1 but is coloured differently because it is a non-metal. Alternatively, you can leave hydrogen white and note it separately in your key. The finished table must be consistent.

如果你采用这种方案，氢通常与第1族放在一起，但因为它是非金属，会使用不同颜色。你也可以把氢留白，并在图例中单独注明。完成的周期表必须保持一致。

5. Metals, Non-metals and Metalloids | 金属、非金属和类金属

Another useful colour layer separates metals, non-metals and metalloids. Metals occupy the left and centre of the table, including alkali metals, alkaline earth metals, transition metals and elements to the left of the staircase line.

另一个有用的颜色层将金属、非金属和类金属区分开来。金属占据周期表的左侧和中间，包括碱金属、碱土金属、过渡金属以及阶梯线左侧的元素。

Non-metals sit on the upper right, except hydrogen. Metalloids lie along the staircase line: boron B, silicon Si, germanium Ge, arsenic As, antimony Sb and tellur
