Sally is making a model of a Mg atom with an atomic mass number of 24. She has balls for the protons, neutrons, and electrons. She has added 6 neutrons to her model. How many more …

A certain atom consists of 16 protons, 18 neutrons, and 16 electrons. What is its atomic number, mass number, and electron configuration? What is atomic number? How is it used to …

If the bond angles at a carbon atom are 120°, how many groups are distributed around the carbon atom? What is the bond angle of a methane molecule that contains four hydrogen atoms …

Question #0a9a2 Chemistry Bohr Model of the Atom Calculations with wavelength and frequency

We know that ionization potential or the first ionization potential is the energy required to remove the outermost electron from a neutral gaseous atom of an element. Similarly second and third …

The "planetary orbit" system of Bohr, even with its quantum energy levels could not survive the coming of quantum mechanics. Details follow... Even as early as the 1910s, physicists were …

The Bohr model applies only to a hydrogen atom or to ions that contain only one electron (hydrogen-like ions). To get a hydrogen-like ion, we must remove all but one of the electrons …

The energy of the nth Bohr orbit for a hydrogen atom, which has Z = 1, is given by the equation En = E1 n2, where E1 - the energy of the 1st Bohr orbit, equal to -1312 kJ/mol; n - the energy …

A photon on a hydrogen atom excited an electron from #n = 1# to make a transition to #n=3#. What is the wavelength (in run) pertaining to this transition and was the transition emitting or …

Rutherford could only account for these phenomena by proposing an atomic model in which MOST of the atom was EMPTY space, and a small, massive, nuclear core contained most of …
