A stairway is a good model for the energy levels in an atom because there is a 'main floor' ( the nucleus ) and steps ( the energy levels ). The nucleus is the start of the stairway of the energy levels, and the other energy levels go off of the nucleus. The first energy level can hold 2 electrons, the second energy level can hold 8. The third energy level can hold 18, and the fourth energy level can hold 32 electrons. In order for an element to be as stable as a noble gas, the outermost energy level has to be full, so sometimes an atom will gain or lose electrons to fill it's outer energy level. Other times it might share electrons with other atoms, so that they don't have to gain or lose a lot of electrons. An example of this would be H2O ( water ). There is one oxygen atom with two hydrogen atoms connected to it, and sharing their electrons with each other.

∙ 11y agoAn atom has discrete energy levels much like the staircase steps. At each step level you have a unique potential energy level. Also you can move between the steps as if you were an electron changing energy levels in discrete steps. The staircase analogy quickly falls apart, but it is a good start for a simple model.

Niels Bohr predicted that the electrons would be found orbiting the nucleus in energy levels that could be compared to what?
Niels Bohr predicted that the electrons would be found orbiting the nucleus in specific energy levels that could be compared to the rungs of a ladder. He proposed that electrons can only exist in these discrete energy levels and that they move between levels by absorbing or emitting specific amounts of energy. This led to the development of the Bohr model of the atom.
The Bohr model of the atom was able to explain the Balmer series because?
differences between the energy levels of the orbits matched the difference between energy levels of the line spectra.
What did Niels Bohr describe electrons as?
The electrons in the Bohr's model of the atom have been compared to the planets of our solar system. While Sun has been compared to nucleus containing nutrons and protons. Make note that the path of the electrons in a stable atom is circular.
Model with dark bands representing energy levels shows where an atom's electrons are most likely to be?
The answer to that would be: An Electron Cloud Model
According the the Bohr model of an atom the single electron of a hydrogen atom circles the nucleus?
in specific energy levels -will

A model that shows comparative energy levels for different feeding levels is called?
energy pyramid
Who created the model of the atom that has quantizied levels of energy?
a vegetarian
How many energy levels does an atom of calcium have based on the bohr model?
Four
What moved in fixed orbits around the nucleus in Bohr's model of a the atom?
Bohr did not speak of fixed LOCATIONS of electrons, he spoke of fixed energy levels. His name for such energy levels was "orbits" or "orbitals."
How the atomic model changed over time?
The atomic model has been refined from "the plum pudding" model,to a nucleus with orbiting electrons,to an awareness of many different sub atomic particles in the nucleus and electrons that are in energy levels,to electrons in sub energy levels and in distinct orbitals with different associated energy and behaviour
The Bohr model of the atom was able to explain the Balmer series because?
differences between the energy levels of the orbits matched the difference between energy levels of the line spectra.

How are atoms and energy related?
Vibration is related to energy. Or on a more complex level, atoms posses electrons, which in the bohr model, are at different energy "levels"
What model shows the amount of energy lost during transference between trophic levels?
Food Web
Model with dark bands representing energy levels shows where an atom's electrons are most likely to be?
The answer to that would be: An Electron Cloud Model
