WebBohr’s model of the hydrogen atom provides insight into the behavior of matter at the microscopic level, but it does not account for electron–electron interactions in atoms with more than one electron. It does introduce several important features of all models used to describe the distribution of electrons in an atom. WebModule 1 Test Remediation page 2 11. The electron orbits in Bohr’s atomic model predict exactly where an electron is located. What do Bohr’s orbits look like?
