Niels Bohr proposed that electrons are arranged in concentric circular paths or orbits around the nucleus. Electrons in a particular path have a fixed energy, thus they do not lose energy and fall into the nucleus. Experiments were base on the hydrogen atom. Results did not hold true for other atoms.
Niels Bohr proposed the idea that electrons have fixed amounts of energy in discrete energy levels in his model of the atom. This led to the concept of quantized energy levels in the atom.
Ben Franklin is the one who said electrons have fixed amount of energy. He said that both the electrons and protons have the constant measure of electricity.
Danish scientist Niels Bohr was the first physicist to hypothesize that electrons occupy specific energy levels, based on his work with the element hydrogen.

Which scientist said electrons travel around the nucleus in fixed energy levels?
Niels Bohr
When electrons absorbs energy they exist for a short time higher energy level. These electrons are said to be?
"Excited", or in an "excited state".
An atom with it's electrons in the lowest possible energy level is said to be?
An atom with its electrons in the lowest possible energy level is said to be in its ground state. The ground state is the most stable configuration for an atom, with electrons occupying the available energy levels starting from the lowest.
When an atom absorbs energy that causes one of its electrons to move to a higher energy level the atom is said to be in?
Excited state
What is meant by excited state of an electron?
When the electrons are at higher energy level,they are said to be excited state.
Which scientist said electrons travel around the nucleus in fixed energy levels?
Niels Bohr
Electrons farther from the nucleus are said to be of what energy?
higher energy
When electrons absorbs energy they exist for a short time at a higher energy level these electrons are said to be?
These electrons are called "excited".
What scientist said electrons move around a central nucleus?
Niels Bohr proposed the model of the atom where electrons move around a central nucleus in fixed orbits. This model helped explain the stability of the atom and the discrete energy levels of electrons.
Electrons farther from the nucleus are said to be of?
Electrons farther from the nucleus are said to be of higher energy levels or higher orbitals. This means they have more energy and are less tightly bound to the nucleus compared to electrons closer to the nucleus.
When electrons absorbs energy they exist for a short time higher energy level. These electrons are said to be?
"Excited", or in an "excited state".
Do electrons have different amounts of energy?
Yes, electrons can have different amounts of energy. In quantum mechanical systems where any particle (not just electrons) are bound, they can only acquire discrete amounts of energy called energy levels. Adding energy to an electron in an atom might cause it to jump to a higher energy level and is then said to be in an excited state; if it were to fall to a lower level it would give up a discrete amount of energy equal to the difference in energy between the two states.
When the maximum number of electrons is an energy level it is said to be what level?
The electrons on the outermost level are called Valence electrons. the usual maximum is 8.
Who was the scientist that said electrons are found in specific energy levels?
That was Niels Bohr
