Question

which of the following lewis dot structures for iodine is correct?

Explanation:

Step1: Determine the valence electrons of iodine

Iodine is in Group 17 (or VIIA) of the periodic table. Elements in this group have 7 valence electrons.

Step2: Analyze each Lewis dot structure

• Structure A: Has too many dots (valence electrons shown are more than 7).
• Structure B: Has too many dots (valence electrons shown are more than 7).
• Structure C: Correctly represents 7 valence electrons (3 pairs and 1 single electron).
• Structure D: Has too few dots (valence electrons shown are less than 7).

Answer:

C.
