Year 7 students can learn about chemical families by looking at the periodic table. This table is organized in rows and columns, which help us understand different kinds of elements.
Rows (Periods): Each row shows a new energy level for electrons. For example, the first row has simple elements like hydrogen (H) and helium (He).
Columns (Groups): The columns show elements that behave similarly. For example:
By looking at these patterns, students can guess how different elements will act in chemical reactions.
For instance, sodium (Na) from Group 1 will react with chlorine (Cl) from Group 17 to make sodium chloride, which we know as table salt.
Understanding these patterns helps students see how the structure of elements relates to their behaviors!
