which of the following is the correct valence dot model for bromine, br?
which of the following is the correct valence dot model for bromine, br?
Answer
Answer: C.
Explanation:
Step1: Locate bromine in periodic table
Bromine is in group 17.
Step2: Determine valence electrons
Elements in group 17 have 7 valence electrons.
Step3: Analyze valence - dot models
Valence - dot model shows valence electrons as dots around the element symbol. Model C has 7 dots around Br, which is correct for bromine.
