no it isn't a good model
a ladder could be used to interpret the emission of light when an electron gets excited, moves to a higher rung, and then falls to a lower or bottom rung. otherwise, it shows nothing of how the atom is constructed, the number of protons, neutrons, electrons, etc
its a good model because it shows you the atom written out. it also helps to show you the valence electron number
A model of the atom is a 3-D structure of the atom's structure.
The rungs of the ladder correspond to the energy levels of the atom. Each rung represents a specific energy level that an electron can occupy within an atom. The higher up on the ladder, the higher the energy level of the electron.
A relay race could be a good model of a series circuit. In any circuit, current flow is the daisy-chaining of electrons from atom to atom.
This is the quantic model of atom.
it gives good represention of what a atom looks like
The Bohr model of the atom was a planetary model.
b-cuz they were just that good
Today the model of atom is based on quantum mechanics.
A model of the atom is a 3-D structure of the atom's structure.
A Millikan atom model doesn't exist.
