Physical Science 7.4c - The Atomic Nucleus

[TasyaAdzkiya]

I know I am late, but thank you so much Mr. Owens! You encapsulated all those complex materials into simple explanations. That is an excellent teacher right there.

Newton provided a mathematical equation for gravity that explained planetary orbits, among other things. That was in the 1600's. Mathematically, it's not that complicated, and can be understood at the high school level.

In the 1900's, Einstein provided a more complete explanation, but it is very difficult mathematically. Einstein's theory is fundamentally different, and also explains more than Newton's.

Two of the great geniuses of all time.

When you have moving charged particles they create magnetic forces which ornate themselves to attract each other, so moving protons would create magnetic forces that would help overcome the repulsion. Also changing the neutron count creates different isotopes.

[donnakuhl]

have you discovered anything new about the nucleus of an atom?

[HamalachMichael]

Every element over element 83 is radioactive? This is not about the atomic number, but the ratio of the atomic number to the mass number of an atom that determines radioactivity, for even a rather light atom of the carbon-14 isotope is radioactive. All elements from 57 to 71 are also radioactive and they are below element 83 as far as atomic number is concerned. Apart from electromagnetism and strong nuclear force being at work in the nucleus, gravity also has an effect, also on the electron...

Mr Issac Newton's gravitational theory has theoretical holes that were basially imposible to comprehend by the people that lived in his time period. For example: "Every massive particle in the universe attracts other massive particles with a force tha's directly proportional to the product of their masses and inversely proportional to the sqauare of their distance". It's simpler to say that worlds are repelled by a cumulative force of 45 millionths of a pound per sq. in. per linear foot.

The jargon related to the atom is abstruce and difficult for students to digest. Protons, neutrons, electrons, positrons, neutrinos, quarks, leptons, byrons, mesons, pions, kaons, and gluons...
I've extrapolated the average diameter of the atom from two real numbers that relate to planet earth and tha's equal to 9 quintiollionths of one millimeter. These tiny axioms interweave their EMERs (Electro Magnetic Emitted Radiation) fields to form molecules.
Atoms are a very simple weave of energy.

This is a great demo. Can you do one explaining the shells/orbitals of protons and neutrons and how they arrange themselves?

[adamrspears]

Concerning the gravitational force, I think that motion is the key. An object that acquires mass has an attraction to any other object(s) with mass. What allows an object of ordinary matter to acquire mass?...motion. If you think about it, all quarks & leptons move. They have motion. Because they have motion, they acquire mass & attract one another. There exists a gravitational pull between particles & objects with motion. E=MC^2 shows us that as an object's velocity increases, so does its mass.

Was watching joe dispenza - rewired ( on the Gaia app) and am episode came on about quantum physics and he started speaking of atoms so I decided to understand it and went down the rabbit hole 😂it’s already 4 am in the morning where I’m at. I must say I’m happy I came accross this video because I ended up studying quarks tonight and it’s quiet fascinating how well you literally explained everything I had questions on. Thanks for summing up by night. Well spoken and super easy to understand your video. I’d love to see more videos pertaining to that and quantum physics.

[JGunlimited]

At 3:20 I disagree. Scientists DO question why... and some make it their focus to understand why... as has been the case historically... the need to understand why / how things work.

Does the nucleus jiggle playing tug of war with forces ?

[HamalachMichael]

Electrons did not grow on their own, they are also a manifastation of a reason, in fact all electrons are a product of a decaying process.

[HamalachMichael]

Actually I thought about the aspect of the ratio of the atomic number to the mass number and its relation to radioactivity and I reason this might not really be the case. Let me introduce you to a problem. If you was to create an airplane and you had to choose whether to use Al or Pb as the building material, which one would you choose? A question, say you drink tea with sugar, would you put sand in the tea also?

[HamalachMichael]

...one might say well gravity is a very weak force and yes, but at this scale it is significant. The atom has an ideal structure and all you need is a little change to the nucleus to change the energy level of the electron orbitals. This has an effect on the atom itself and how it interacts with other atoms and hence in chemical processes and structure of molecules etc. In the end what goes on in the nucleus has effect on entire universe. Change the nucleus, you change the universe.

[kmoses]

You forgot to mention the dark force ( as in star war)

[meenakshiparashar]

Sir my question to you is that: when we move from left to right in period why atomic size get reduced ??? .... I m from india

[TcaciVera]

5:00 Ok, you said that the strong force has a short range, why the force is the same on the both sides? And then you said that there is enough distance for the force to weak.
I just want to understand, can you explain me?

[HamalachMichael]

All atoms of all elements decay? Would you build a house made up of bricks that fall apart? Who with such intelligence to create everything from foundamental particles to entire galaxies and with power that holds the nucleus, governs solar systems and entire galaxies is capable of an imperfection in the design of the entire universe?

[MrKhachik]

@derekowens Thank you for clarification
