If the quantum number l (lower case L) has a value of 1, the allowed values of ml are -2, -1, 0, 1, 2 -1, 0, 1 0 and 1 0, 1, 2
ine sizes and snapes or the nyarogen atom orditais 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. In the hydrogen atom, what is the total number of nodes present in a 6d orbital? total nodes: How many of the nodes are spherical (radial)? spherical nodes: How many of the nodes are planar (angular)? planar nodes: nodes nodes nodes s orbital p orbital d orbital forbital
Calculate the de Broglie wavelength of a Li atom travelling with a velocity of 7.01 x 103 m/s. Give your answer in picometers (1 pm = 1 x10-12 m). Input your answer with 2 decimal places. Do NOT input units. For example, if your answer is 7.931643x10-12 m (which equals 7.931643 pm), enter your answer as 7.93
