In this lesson, you learned about the Bohr model of the atom. The Bohr model below shows a phosphorus (P) atom. Write a paragraph describing how many valence electrons the atom has and why Bohr models are still useful to predict bonding of atoms, even though Bohr models do not correctly show the location of electrons in an atom.
