Step 1:I'll solve this step by step:
Step 2:: Understand the Periodic Table Position
- Fluorine (F) is located in Group 17 (the halogen group) on the periodic table - Its atomic number is 9 - Fluorine has 7 valence electrons in its outer shell
Step 3:: Determine Electron Configuration
- Fluorine's electron configuration is $$1s^{2} 2s^{2} 2p^{5}
- It needs 1 more electron to complete its outer shell and achieve a stable noble gas configuration
Step 4:: Predict Ion Formation
- Fluorine tends to gain 1 electron to achieve a stable octet (8 electrons in its outer shell) - When it gains 1 electron, it becomes a negatively charged ion - The charge will be - 1
Step 5:: Verify the Charge
- Net charge: $$9 - 10 = -1
- Number of protons remains 9 - Number of electrons becomes 10
Final Answer
The fluorine ion has a charge of - 1, forming the fluoride ion (F⁻).
