Quantized. (Number 4 if you are using what I think you are using.)
It was Ernest Rutherford who discovered that atoms are mostly composed of empty space with electrons orbiting a very dense nucleus.
Benjamin Franklin
An atomic theory that patches up the holes in Ernest Rutherford's own. Bohr's theory states that electrons give off energy in bunches, not continously, so as long as the electrons remain in a stable orbit they will have the same amount of energy.
He came up with his model of the hydrogen atom, containing this idea, in 1913. That's almost exactly 100 years ago. Neils Bohr came from Denmark and they will be celebrating this centenary, in Denmark.
Electrons in Bohr's model of the atom
Bohr suggested that electrons circle the nucleus in quantized orbits or energy levels. This is known as the Bohr model of the atom.
Niels Bohr
The scientist who discovered that atoms have an energy level is Niels Bohr in 1913. According to his model electrons move around the nucleus much the same as the planets rotate around the sun.
He suggested that electrons must be orbiting the nucleus in a certain fixed energy level or shells He also thought that each electron has it's own level of energy, and rotates the Nucleus -- Jopika
Niels Bohr first suggested that electrons orbited the nucleus in fixed energy levels.
Niels Bohr first suggested that electrons orbit the nucleus in fixed energy levels in his model of the atom in 1913. This model helped to explain the stability of atoms and their emission spectra, leading to important developments in quantum mechanics.
The Bohr model describes atoms as having a nucleus surrounded by electrons in fixed energy levels. For neon, which has 10 electrons, the Bohr model would show two electrons in the first energy level, and eight electrons in the second energy level. The electrons in the outermost energy level determine neon's chemical properties.
The scientist who first proposed that electrons existed in only certain energy levels around the nucleus was Niels Bohr. His model of the atom, known as the Bohr model, introduced the concept of quantized energy levels and provided a framework for understanding the behavior of electrons in atoms.
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.
valence electrons are the electrons found in the outermost energy level of bohr diagram for an element.
Niels Bohr introduced the idea that electrons can jump from one energy level to another in his model of the atom, known as the Bohr model. This concept was a key development in understanding atomic structure and the behavior of electrons in atoms.
Atoms are the building blocks of matter, and energy is the capacity to do work. Energy can be stored within atoms in the form of electromagnetic energy due to the movement of electrons. In chemical reactions, atoms can release or absorb energy as they rearrange into different molecules.
