the lewis dot diagram for an unidentified element is shown below. which element could x represent? iron chlorine silicon oxygen
Answer
Answer:
B. chlorine
Explanation:
Step1: Count valence electrons
The Lewis - dot diagram shows 7 dots around the element symbol, indicating 7 valence electrons.
Step2: Check valence electrons of options
- Iron is a transition metal and does not typically follow the octet - rule based on valence electrons shown in a simple Lewis - dot diagram.
- Chlorine has 7 valence electrons. Its electron configuration is [Ne]3s²3p⁵.
- Silicon has 4 valence electrons. Its electron configuration is [Ne]3s²3p².
- Oxygen has 6 valence electrons. Its electron configuration is [He]2s²2p⁴. So the element X could be chlorine.
