The formula for this is E = hu, where E is the energy of the radiation, h is a universal constant known as Planck'sconstant, and u is the frequency of the radiation. This proposal-that the energy contained within a light beam is transferred in individual units, or quanta-contradicted a hundred-year-old tradition of considering light energy a manifestation of continuous processes.
what did marsden contribute to the evolution of the atom
He discovered that the atom contained smaller particles called electrons.
In Bohr's atomic theory, Planck's constant divided by 2π represents the angular momentum of the electron in a stable orbit around the nucleus. This value is used to quantize the angular momentum of the electron in discrete levels, as proposed by Bohr in his model of the atom.
A neutral particle in an atom is typically found in the nucleus, such as a neutron. Neutrons have no charge and contribute to the atomic mass of the atom.
The part of the atom that has a negative charge is the electron. Electrons are located in the electron cloud surrounding the nucleus of an atom and contribute to the atom's overall negative charge.
Subatomic particles are particles that are smaller than an atom, such as protons, neutrons, and electrons. They make up the structure of an atom and contribute to its properties and behavior. These particles are fundamental to understanding the world of particle physics.
what did marsden contribute to the evolution of the atom
we were feared of due to the technology of the atom bomb.
A coordination number table provides information about the number of atoms or ions surrounding a central atom in a compound. It helps in understanding the geometry and structure of the compound.
you answer it for me !!
i s obvious that contributes the think that's said in the real life for give us all this information
442 BC
Bohr improved Planck's theory by incorporating the concept of quantized energy levels for electrons in atoms. He proposed that electrons could only exist in certain distinct energy levels, which helped explain the stability of atoms and the emission/absorption of light in atomic spectra. This led to the development of the Bohr model of the atom.
He discovered that the atom contained smaller particles called electrons.

The subatomic particles that contribute most almost no weight to an atom are electrons at various energy levels. Isotopes of the same element differ from each other only by the number of neutrons.
A neutral particle in an atom is typically found in the nucleus, such as a neutron. Neutrons have no charge and contribute to the atomic mass of the atom.
