how many dots belong in the electron dot diagram of a boron (b) atom?\no three\no five\no eight\no thirteen
how many dots belong in the electron dot diagram of a boron (b) atom?\no three\no five\no eight\no thirteen
Answer
Explanation:
Step1: Determine boron's atomic number
Boron has an atomic number of 5.
Step2: Find valence electrons
The electron - configuration of boron is 1s²2s²2p¹. The number of valence electrons (electrons in the outermost shell) is 3. In an electron - dot diagram, we represent valence electrons with dots.
