### Understanding Group 1 Reactivity in the Periodic Table**Reasoning:** Why does reactivity increase down Group 1? Answer the following questions to help you as you type your response:1. **How many valence electrons do they have?**2. **How does atomic radius change down the group?**3. **As atomic radius changes, what happens to the electrostatic force of attraction between the valence electrons and protons?**4. **What happens to the valence electrons as they react? What are the alkali metals trying to form?**Exploring these questions can provide an insight into the chemical properties of Group 1 elements, also known as alkali metals, listed below with their respective atomic numbers:- **Li (Lithium)**- **Na (Sodium)**- **K (Potassium)**- **Rb (Rubidium)**- **Cs (Cesium)**### Detailed Diagrams and Concepts**Diagrams of Electronic Configurations:**- **Li:** ![Li Diagram](diagram) Lithium (Li) with atomic number 3 has an electron configuration of 2, 1.- **Na:** ![Na Diagram](diagram) Sodium (Na) with atomic number 11 has an electron configuration of 2, 8, 1.- **K:** ![K Diagram](diagram) Potassium (K) with atomic number 19 has an electron configuration of 2, 8, 8, 1.- **Rb:** ![Rb Diagram](diagram) Rubidium (Rb) with atomic number 37 has an electron configuration of 2, 8, 18, 8, 1.- **Cs:** ![Cs Diagram](diagram) Cesium (Cs) with atomic number 55 has an electron configuration of 2, 8, 18, 18, 8, 1.- **Fr:** ![Fr Diagram](diagram) Francium (Fr) with atomic number 87 has an electron configuration of 2, 8, 18, 32, 18, 8, 1.**Explanation of Graph/Diagram:**- Each diagram depicts an element from Group 1 with a series of concentric circles representing electron shells around a central nucleus.- The atomic number increases as
