how many dots belong in the electron dot diagram of a boron (b) atom?\nthree\nfive\neight\nthirteen
Answer
Explanation:
Step1: Recall boron's atomic number
Boron has an atomic number of 5.
Step2: Determine valence electrons
The electron - configuration of boron is 1s²2s²2p¹. The valence electrons are in the outermost shell (n = 2 in this case), and there are 3 valence electrons (2s²2p¹: 2 + 1=3).
Step3: Relate to electron - dot diagram
In an electron - dot diagram, the number of dots represents the number of valence electrons.
