It was given by de Broglie.
4. Photoelectric Effect
When the light with energy hits the electrons releases light in the form of a wave is a photoelectric effect.
The scientist discovered that different waves tell about interference, diffraction and scattering
The waves can work in water, metal or any sort of object.

Useful facts you need to know
Atomic structure: some important concepts you may want to know
Dalton's atom
Elements are made of invisibly small particles. These particles are called atoms.
All atoms of one element are identical but different elements have different types of atoms
Atoms cannot be created or destroyed.
Compounds are formed when atoms of different elements combine in a simple ratio (to give molecules)
Rutherford's atom
The atom has positively charged the central part
Negatively charged electrons revolve around the nucleus.
Atom is neutral (due to equal positive and negative charges)
Bohr's atom
The electron travels around the nucleus in the specified permitted circular orbits and in no others (i.e. electrons are at a fixed distance from the nucleus with fixed energy)
The electron does not radiate energy when it stays in one orbit
When an electron moves from one energy level to another, it radiates or absorbs energy. If it moves towards the nucleus, energy is radiated and if it moves away from the nucleus, energy is absorbed.
For an electron to remain in its orbit the force of attraction between the electron and nucleus must be equal to the centrifugal force
The angular momentum of an electron orbiting around the nucleus is equal to nh/2 π.
Some FAQS are
Here expert will help you with various topics that are involved in the atomic structure some of them are explained below;
1. What are protons, electrons and neutrons?
Protons
All are positively charged.
All protons are identical.
Formula:
Atomic number= number of protons.
It is located in the nucleus.
Neutrons
There is no charge (neutral charge)
All are identical
Formula:
mass number= number of protons+ number of neutrons
It is located in the nucleus.
Electrons
All are negatively charged.
It is located in orbitals.
2. Principal quantum number?
Principle quantum number (n)
K = 1
L=2
M=3
N=4
3. Shapes and size of orbitals?
Shapes of orbitals are
S- Orbital = spherical
P- Orbital (l=1) = dumbbell
D-orbital (l=2)= double dumbbell
4. Nodal points and planes?
Number of radial nodes = n – l – 1
Number of angular nodes = l
Total number of nodes = n – 1
Nodal planes are planes of zero per cent in finding the electron
5. What is a Quantum number?
The shells and subshells are expressed in a different numbers called quantum numbers.
6. Success of Bohr's model?
- Bohr's atomic model introduces quantum principles to classical physics. It is the biggest contribution of this model.
- The model could explain the spectrum emitted by hydrogen atoms. It is also applicable to hydrogen-like atoms as He, Li, Be etc.
7. Failure of Bohr's model?
- It cannot explain Zeeman Effect.
- It cannot explain the Stark effect
- It cannot explain the spectra of heavier elements.
8. What is Zeeman Effect?
If a substance emitting a line spectrum is placed in the magnetic field, a spectral line splits up into several closely spaced lines it is called the Zeeman Effect.
9. What is the stark effect?
If a substance emitting a line spectrum is placed in an electric field, a spectral line splits up into several close space lines it is because the electric field can split the energy level with the same energy into energy levels with higher and lower energy.
10. What is a Matter-wave?
The waves associated with the particles such as electrons, atoms and molecules are called matter waves. The larger the particle, the smaller the wavelength of the wave associated with it.
11. What is the Heisenberg uncertainty principle?
If the position of an electron is measured more precisely, its velocity can be measured less precisely. If the electron is measured more precisely, its position can be measured less precisely. Mathematically, Δx ≥ h 4π
Where h is Planck constant,
Δx is uncertainty in the position.
12. Schrödinger's wave equation?
It is the basic equation of quantum mechanics. The equation is,
∇2ψ+8π2 m (E – U) ψ/h 2=0, this is a time independent equation.
The solution of this equation gives a satisfactory description of an atom. It provides information about the probability of finding an electron in a particular position or particular volume space.
The solution to the wave equation gives the wave function. The wave function has no meaning itself but gives the probability of finding an electron at a point in space.
