Who discovered the nuclear model?
Ernest Rutherford created the nuclear model of an atom!
Why K L M N O P Q in model of Bohr?
Oh, dude, you're asking about the Bohr model of the atom, huh? So, like, in that model, the letters K, L, M, N, O, P, Q represent the energy levels or shells where electrons can be found. It's like a way to organize where those little electron party animals hang out around the nucleus. So, yeah, those letters just help us keep track of which energy level the electrons are chilling on.
How many electrons are in the nucleus of an atom with an atomic number of 20?
None. Electrons are found in energy levels outside the nucleus, not in it. An atomic number of 20 tells you there are 20 protons in the nucleus of an atom, and 20 electrons in energy levels (or shells or orbitals depending on which model of the atom you are using) outside the nucleus.
What does model mean science term?
A model is a physical three dimensional object that is created too appear as an object which is usually too small or large.
How many energy levels does an atom of calcium have based on the bohr model?
An atom of calcium in the Bohr model has four energy levels. These energy levels are designated by the quantum numbers n=1, 2, 3, and 4, corresponding to the first, second, third, and fourth energy levels, respectively.
A model that shows comparative energy levels for different feeding levels is called?
The model is called an energy pyramid. It illustrates the flow of energy through a food chain, showing how energy decreases as it moves from one trophic level to another.
According the the Bohr model of an atom the single electron of a hydrogen atom circles the nucleus?
According to the Bohr model, the single electron of a hydrogen atom moves in circular orbits around the nucleus at specific energy levels. The electron can only occupy certain quantized energy levels and emits energy when transitioning between levels.
How ionization energy can be explained by bohr's atomic model?
In Bohr's atomic model, electrons orbit the nucleus in specific energy levels. Ionization energy is the energy required to remove an electron from an atom. Electrons in higher energy levels have greater ionization energy because they are held more tightly by the nucleus.
What did de Broglie propose to account for the fixed energy levels in Bohr's model of the atom?
De Broglie proposed that electrons in Bohr's model of the atom have wave-like properties, which helps explain the fixed energy levels.
Which scientists postulated that the sharp lines in the emission spectra of elements are caused by electrons moving from high energy levels to low energy levels?
Niels Bohr proposed this model in 1913. His model of the atom suggested that electrons occupy specific energy levels and emit or absorb energy in quanta when they move between these levels, corresponding to the sharp lines observed in the emission spectra of elements.
What is A model that shows comparative energy energy levels for different feeding levels?
A model that illustrates comparative energy levels for different feeding levels is typically represented by a trophic pyramid. This pyramid depicts the energy flow through an ecosystem, with producers at the base, followed by primary consumers, secondary consumers, and so on, each level representing a different feeding level. As energy is transferred from one trophic level to the next, approximately 90% of the energy is lost as heat, leading to fewer organisms and less energy available at higher levels. This model highlights the inefficiency of energy transfer and the importance of each trophic level in maintaining ecosystem balance.
Where can electrons not reside according to the bohr model?
In between any of the energy levels, electrons have to be in an energy level and prefer to be at the lowest energy level possible. Additional information: Electrons in the first energy level can only have two attached and in any energy level after that cannot exceed more than 8
How did Neils Bohr revise Rutherfords atomic model?
Niels Bohr revised Rutherford's atomic model by incorporating the idea of quantized electron energy levels, proposing that electrons orbit the nucleus in specific energy levels or shells. This model explained the stability of atoms and how they emit and absorb light energy in discrete amounts.
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.
Who came up with the concept of energy levels?
The concept of energy levels in atoms was developed by Niels Bohr in 1913 as part of his atomic model. Bohr proposed that electrons orbit the nucleus in specific energy levels, and that they need a specific amount of energy to jump between these levels.
What moved in fixed orbits around the nucleus in Bohr's model of a the atom?
Electrons moved in fixed orbits around the nucleus in Bohr's model of the atom. These orbits were quantized, meaning they had specific energy levels, and electrons could jump between these orbits by either absorbing or emitting energy.
