QUANTUM NUMBERS

-
"It is a value that is used when describing the energy level available to atoms and molecules". There are four quantum numbers as following:-

• Principle Quantum Number- The energy of electrons in an atom depends on principle quantum number. It is denoted 'n'.
The principle quantum no.determines the energy of electron and size of the shell. 
n= 1,2,3,4,5......
Electron shell= K, L, M, N, O...... 
Object of principle quantum number, it gives us the energy and radial distance. 

• Azimuthal Quantum Number- It is the quantum no.for an atomic orbital that determines it's angular momentum and describes the shape of the orbital, it is also know as Orbital Quantum Number. Denoted by 'l'.
Object it gives us the magnetude of angular momentum of electron. 

• Magnetic Quantum Number- It is deals with the direction of angular momentum with respect to some fixed derection in space(that is the direction  along with a magnetic field is applied). It is denoted by 'ml'.

• Spin Quantum Number- It is the quantum number that parameterizes the intrinsic angular momentum of a given particle. 
denoted by 's'.

  INTERNATIONAL SPACE STATION(ISS) PC - NASA Five space agencies including NASA, JAXA, ROSCOSMOS, CSA, ESA have contributed to the space station assembly. The International Space Station is larger than a six-bedroom house with six sleeping quarters, two bathrooms, a gym, and a 360-degree view bay window. In 24 hours, the space station makes 16 orbits of Earth, traveling through 16 sunrises and sunsets. Peggy Whitson  set the U.S. record for spending the most total time living and working in space at 665 days on Sept. 2, 2017. To mitigate the loss of muscle and bone mass in the human body in microgravity, the astronauts work out at least two hours a day. The solar array wingspan (356 feet, 109 meters) is longer than the world’s largest passenger aircraft, the Airbus A380 (262 feet, 80 meters). pc-NASA The space station is 356 feet (109 meters) end-to-end, one yard shy of the full length of an American football field including the end zones. A spacecraft can arrive at the s...

Molarity : It is a solution which is the number of moles of the solute present in per liter of solution.  (प्रति लीटर विलयन में घुलित विलेय पदार्थ के मोलों की संख्या को विलयन की मोलरता कहते हैं)।  यह किसी निश्चित ताप पर ही हो सकता है।  •  It is denoted by 'M'. Formula :   •    M = (number of moles of solute/volume of solution in liter)                          Or                     M = n/v Unit : mol/liter or mol/L       Formality : It is used to solve the concentration of ionic compounds solutions. Denoted by 'F'. We could use  gram formula mass for ionic compounds. Because they have no discrete molecules e.g. molecular mass word is not valid for that kind of compounds.  "किसी निश्चित ताप पर प्रति लीटर विलयन में घुलित आयनिक पदार्थ के ग्राम सूत्र द्रव्यमान की संख्या विलयन की उस ताप पर फॉर्मलता कहलाती है।" (Gram ...
