can you tell me about structure of atom and electric spectrum and about quantum numbers

Structure of an atom:

• Atoms are divisible into sub-atomic particles such as protons, neutrons and electrons.
• Atoms can be created and destroyed by nuclear fusion and nuclear fission.
• The atoms of an element may not be alike in all respects, as seen in the case of isotopes (i.e. atoms of the same element with the same atomic number but different mass numbers).

Spectrum:

When a white light is passed through a prism, it splits into a series of coloured bands known as spectrum.

Spectrum can be classified into two types such as continuous spectrum and line spectrum.

The spectrum which consists of all the wavelengths is called a continuous spectrum.

 A spectrum in which only specific wavelengths are present is known as a line spectrum.

It has bright lines with dark spaces between them.

 

Electromagnetic spectrum is a continuous spectrum. It consists of a range of electromagnetic radiations arranged in the order of increasing wavelengths or decreasing frequencies. It extends from radio waves to gamma rays.

 

Quantum numbers:

There are a set of four quantum numbers which specify the energy, size, shape and orientation of an orbital.

 These are 

• Principal quantum number (n)
• Azimuthal quantum number (l)
• Magnetic quantum number (ml)
• Electron spin quantum number (ms)
