The electron shell model is really interesting because it helps us figure out why elements act the way they do. Let’s break it down:
Energy Levels: Electrons are arranged in layers, called energy levels or shells, around the nucleus (the center of the atom). The first shell can hold 2 electrons, the second can hold 8, and this pattern continues. This setup affects how these elements react with each other.
Valence Electrons: The electrons in the outermost shell are called valence electrons. These special electrons decide how an element will connect with other elements. For example, elements in Group 1 only have one valence electron, which makes them very reactive!
Periodic Trends: When you look across the periodic table, you can see patterns in things like size and how reactive elements are. This is because of how these shells are filled. For instance, noble gases have full outer shells that keep them stable and less likely to react.
In summary, understanding electron configuration helps us see why elements have different properties!
