课程名称：原子结构 AS 级 (9701) 课程概述：本课程旨在帮助学生理解 AS 级化学，特别是为准备国际剑桥 AS 级化学考试的学生而设计。该课程遵循剑桥国际 AS 级大纲，详细逐步讲解大纲的第一部分，即原子、分子和化学计量。课程将包含以下学习成果： 1. **原子的粒子** - 学生将学习原子的组成，了解质子、中子和电子的相对电荷和质量，并讲解这些粒子在通过电场时的行为。 2. **原子的核** - 解释同位素的定义。 3. **能量层级及亚壳** - 讲解不同类型的量子能量亚壳（s、p 和 d）及其能量层级。 4. **轨道形状** - 解释 s 轨道和 p 轨道的形状。 5. **电子排布** - 教授学生如何在考试中为给定元素写出电子排布。 6. **第一电离能及影响因素** - 简要解释第一电离能及其影响因素。 7. **电离能在周期和族中的趋势** - 解释电离能在周期中的增加和在族中的减少原因。 该课程通过详尽的讲解，使学生能够轻松理解原子结构相关内容，为他们的考试做好充分准备。
The purpose of this course is to help those students in understanding AS Level Chemistry and is especially designed for those students preparing for International Cambridge AS Level Chemistry Examinations. The code this course follows is 9701.This course will follow the Cambridge International AS Level syllabus, In this course, everything will be explained in detail step by step, so students can easily understand about the first part of the syllabus that is Atoms, molecules and stoichiometry.This course will consist of the following learning outcomes:2.1- Particles in the atom- students will learn the composition of an atom. They will also learn about the relative charge and masses of protons, neutrons and electrons. The behavior of a beam of protons, neutrons and electrons when passing through an electric field will also be explained.2.2- The nucleus of the atom- Definition of isotopes will be explained.2.3- Energy level and subshells- what are different types of quantum energy subshells ( s, p and d), and energy levels of this subshells will be explained.2.3- Shape of orbitals- shape of s and p orbitals will be explained.2.3- Electronic configuration- in this topic students will be explained how to write electronic configuration of a given element when asked in the examination.2.3- First ionisation energy and the factors affecting them: here first ionisation energy will be explained briefly and also the factors that affect them too.2.3- Ionisation energy trends across a period and down a group- reasons why ionisation energy increases across a period and decreases down a group will be explained.
