Question: how many valence electrons are there in silicon which has an atomic number of 14?
Answer: Step 1: The atomic number of silicon is 14 so it has 14 electrons in it. Step 2: The electronic configuration of silicon is as follows: Step 3: The highest principal energy level is 3 so the electrons present in 3s and 3p orbital are the valence electrons. So there are 4 valence electrons in silicon atom.
