Alpha rays :-

Nature: He nuclei represented as   2He⁴  or He²+

Mass :  4 a.m.u or  6.642 × 10^ –27 kg

Charge :Positive charge of +2 units

Penetrating power : Minimum -0.1 mm thick aluminum foil can stop it.

Ionising power :  Maximum.


Beta rays:-

Nature: Stream of electron represented as -1e⁰.

Mass :  0.000548597 a.m.u. or 9.1 x 10-31 kg

Charge :Negative charge of –1 unit.

Penetrating power : It is stopped by 5 mm thick Aluminum foil.

Ionising power : Less than Alpha but more than Gamma rays.


Gamma rays:—

Nature : Electromagnetic waves of very short wavelengths.

Mass : No mass

Charge : 0

Penetrating power : Maximum — even 750 mm thick pb plate cannot stop it.

Ionising power : very Low.

I Wonder, By Jeannie Kirby [ poem ]

By -
                      I Wonder  I wonder why the grass is green, and why the wind is never seen ? Who taught the birds to build a nest,    And told to trees to take a rest ? O,  When the moon is not quite round, Where can the missing bit be found ? Who lights the stars, when they blow out,    And makes the lightning flash about ? Who paints the rainbow in the sky, And hangs the fluffy clouds so high? Why is it now, do you suppose, That Dad won't tell me , if he knows?                                                by  Jeannie Kirby

The principal quantum number (n), ●Quantum Numbers, -part-1

By -

  Quantum numbers :  the concept of quantum numbers was first introduced by Neils Bohr, 1. principal (n)   2. Azimuthal (l)  3. Magnetic  (m)   4.spin  Bohr's model predicts only  one quantum number (n), But the quantum mechanical model of atom introduces three more quantum numbers, As a matter of fact, in order to have a complete knowledge of the energy  states of electron in an atom, four quantum numbers are required.  The size and shape of electron  orbits, orientation  of orbitals in the magnetic field  and the spin of an electrons about its own  axis — are all characterized by a thorough knowledge  of the four quantum numbers. [1.] The principal quantum numbers (n) : • thus " n "  indicates the size of the electron orbit.  • The principal quantum number determines  the energy of the electron present in any shell.  it also indicates how the probability of finding the electron var...

  when I open my WhatsApp,  and I see  my friend (Danish)  text me about  this incident that Black panther Aka Chadwick Boseman is no more between us. From our heart he's our real king🤴. not only because he's  the king of Wakanda also because he fought against cancer for few year. and still worked.   he's the real king. Our King.💔  I see official post from the marvel.   I really  felt  bad, and heart Broken after Hearing this news.
