Why must an electron absorb a fixed amount of energy to jump from its ground state to an excited state?
An electron must absorb a fixed amount of energy to jump from its ground state to an excited state because energy levels in an atom are quantized. This means that electrons can only occupy specific energy levels, and the energy difference between these levels corresponds to a precise amount of energy that must be absorbed for the transition to occur. If the energy absorbed is not equal to this specific amount, the electron cannot transition to a higher energy state, resulting in no excitation.
How does a Bohr model illustrate electron placement within an atom?
The Bohr model demonstrates electron placement by showing electrons orbiting the nucleus in specific energy levels, or "shells". Each shell can only accommodate a certain number of electrons, with the electrons closest to the nucleus having lower energy levels. The model helps us understand how electrons are organized and distributed within an atom.
What are the basic assumption of the Bohr model?
The basic assumptions of the Bohr model of the atom are that electrons orbit the nucleus in fixed, quantized energy levels without emitting radiation, electrons can only exist in these specific energy levels, and that energy is absorbed or emitted when an electron jumps from one energy level to another.
What is the region around a necleus where an electron might be found?
The region around a nucleus where an electron might be found is called an electron cloud or orbital. This area represents the probability distribution of an electron's position, rather than a fixed path. Electrons occupy various energy levels and shapes of orbitals, which can be spherical, dumbbell-shaped, or more complex. The concept reflects quantum mechanics, where the precise location of an electron cannot be determined, only the likelihood of finding it in a given region.
What is the fixed paths of electrons called?
energy levels

In what way electrons quantized?
They have fixed energy values.
What happens when a 3s electron becomes a 2s electron?
Any electron is not fixed to any sub-shell or orbital. If you provide sufficient energy to an electron, it would make transition to any of the higher energy orbitals and then come back to the lower orbitals radiating energy.
Electrons exist only at fixed levels of potential energy However if an atom absorbs sufficient energy a possible result is that?
An electron may move to an electron shell farther out from the nucleus.
What is the description of the Bohr model of the atom?
Each electron in an atom is in an orbital (*NOT* an orbit!!) at a specific energy level from the positive nucleus. The energy levels of these orbitals are fixed -- an electron can go from orbital 's' to orbital 'p', but it can't go halfway between these two orbitals. When an electron in an atom goes from a higher orbital to a lower one, then the atom must give off an amount of energy, that is exactly the difference in energy in the two levels. For a hydrogen atom, these orbital levels are fixed by the fact that the angular momentum of an electron in an orbital is quantized -- ie, it comes in exact multiples, but not fractions, of a minimal amount.
What is the best description of an bohr model of an atom?
