Arrangement Of Elements
Akopọ
The periodic table is chemistry's master map. Over a hundred elements are laid out in a single grid, and their position alone tells you a remarkable amount about how each one behaves. Learning to read this map is one of the most powerful skills in the whole subject.
In this lesson you will learn how the elements are arranged in order of increasing proton number, what the rows and columns are called, and why elements in the same group share similar properties. This pattern is the key to predicting and explaining the behaviour of elements.
Awọn Afojusun
- Describe the Periodic Table as an arrangement of elements in periods and groups and in order of increasing proton number / atomic number.
- Describe the change from metallic to non-metallic character across a period.
- Describe the relationship between group number and the charge of the ions formed from elements in that group.
- Explain similarities in the chemical properties of elements in the same group of the Periodic Table in terms of their electronic configuration.
- Explain how the position of an element in the Periodic Table can be used to predict its properties.
- [Supplement] Identify trends in groups, given information about the elements.
