which dot structure correctly shows the valence electrons in boron?
Answer
Brief Explanations:
Boron has an atomic number of 5. Its electron - configuration is 1s²2s²2p¹. The valence electrons are in the second shell (n = 2), and there are 3 valence electrons. In Lewis dot structures, we represent valence electrons as dots around the symbol of the element.
Answer:
The third dot - structure (the one with 3 dots around the 'B') correctly shows the valence electrons in boron.
