s orbital The sizes and shapes of the hydrogen atom orbitals were revealed through graphical analysis of the corresponding wave functions. These wave functions also predict areas in which the electrons have a zero probability of being found These areas are known as nodes. Nodes in the hydrogen atom orbitals exist either as spherical (radial) nodes or planar (angular) nodes. p orbital In the hydrogen atom, what is the total number of nodes present in a 6f orbital? d orbital...

In lab we studied the Bohr model of the hydrogen atom which is verified exactly with quantum mechanical calculations. From quantum mechanics we also find that Bohr’s equation can be used for any one-electron cation like He+, Li2+, Be3+ etc, by including the atomic number, Z, of the cation in the equation with Bohr’s constant (): En= -Z2n2(Accurate for any one-electron cation with atomic number Z) Use this equation to calculate the energy (J) of the first and second energy...
