Which is the correct Lewis structure for nitrogen trifluoride?
Solution 9SAQ Let’s try to demonstrate the correct answer is for letter c) Step 1 of 3 Lewis structures represent the valence electrons that an atom shares or transfer when forming a bond in order to attain noble gas electron configuration. Nitrogen belongs to the group VA, so it has 5 electrons in its valence shell and it needs 3 electron to respect the octet rule. Step 2 of 3 Fluorine has seven electrons in its valence shell because it belongs to group VII A. So it needs one electron to complete the valence shell and respect the octet rule.
