Question: how many valence electrons are in the electron-dot structures for the elements in group 4a?
Answer: Group 4A elements have 2 valence electrons in an s orbital and 2 valence electrons in p orbitals. Group 5A elements have 2 valence electrons in an s orbital and 3 valence electrons in p orbitals. Group 6A elements have 2 valence electrons in an s orbital and 4 valence electrons in p orbitals.
