Main Teaching Activities and Time Allocation 主要教学活动和时间分配

Recap: Periodic Table Data Interpretation: Teacher recaps how to find mass number (P+N), proton number (P), and thus calculate N and E (E=P) using Helium and Boron examples. Practice with Lithium, Sodium, and Iron.

复习：周期表信息解读： 教师回顾如何利用氦和硼的例子从周期表中找出质量数（P+N）、质子数（P），并计算中子数（N）和电子数（E=P）。并与学生练习了锂、钠和铁。

Introduction to Electron Configuration and Shell Rules: Introduction of the nucleus, electron shells, and the rules for electron filling (Shell 1 max 2, Shell 2 max 8, Shell 3 max 8). Teacher demonstrates filling Sodium's 11 electrons (2, 8, 1) and explains the rule that shells must be filled sequentially.

电子排布及电子层规则介绍： 介绍原子核、电子层以及电子填充规则（第一层最多2个，第二层最多8个，第三层最多8个）。教师演示填充钠的11个电子（2, 8, 1），并解释必须按顺序填满电子层的规则。

Practice: Drawing Structures and Writing Configurations: Student practices drawing the structure and writing the configuration for Magnesium (result: 2, 8, 2) and Neon (result: 2, 8). Teacher explains the significance of Neon's full outer shell.

练习：绘制原子结构图和书写电子排布： 学生练习绘制镁的结构图并写出电子排布（结果：2, 8, 2），然后练习氖（结果：2, 8）。教师解释了氖具有满外层的重要意义。

Connecting Period/Group to Electron Configuration: Teacher explains Group number = outer shell electrons (with Group 0 exception for full shells) and Period number = number of shells. Student successfully deduces configurations for Calcium (Period 4, Group 2 -> 2, 8, 8, 2) and Silicon (Period 3, Group 4 -> 2, 8, 4).

周期/族号与电子排布的联系： 教师解释族号=外层电子数（第0族满壳层是例外），周期号=电子层数。学生成功推导出钙（第4周期，第2族 -> 2, 8, 8, 2）和硅（第3周期，第4族 -> 2, 8, 4）的电子排布。

Stability and Preview of Bonding: Teacher explains that a full outer shell leads to high chemical stability and unreactivity (Noble Gases do not form bonds). Preview of the next topic: Covalent, Ionic, and Metallic bonding.

稳定性与化学键预习： 教师解释满外层导致高化学稳定性和不活泼性（惰性气体不形成化学键）。预告下一主题：共价键、离子键和金属键。
