Step 1:Let's solve this step by step:
Step 2:: Understand Valence Electrons
- Fluorine is located in Group 17 (the halogen group) on the periodic table - It has 7 valence electrons in its outer shell
Step 3:: Determine Electron Configuration
- Fluorine wants to achieve a stable electron configuration like noble gases - Noble gases have a full outer shell of 8 electrons - Fluorine needs 1 more electron to complete its octet
Step 4:: Predict Ion Formation
- To achieve 8 valence electrons, fluorine will gain 1 electron - When an atom gains electrons, it becomes a negative ion (anion) - The charge will be 1– to balance the electron gain
Step 5:: Verify the Charge
- Fluorine starts with 7 valence electrons - It gains 1 electron to reach 8 electrons - This results in a 1– charge
Final Answer
Explanation: Fluorine will form a 1– ion by gaining one electron to complete its outer electron shell, achieving a stable noble gas configuration.
