Atoms (part #2)

Hi guys in this post we are going to talk about the four fundamental forces.

The first force is gravity. You might be surprised but it is the WEAKEST of the four forces 😱. FUN FACT: no matter what anything is it will always have gravity. You may not realize it. The smaller amount of mass you have the less gravity there will be.

In this drawing I drew two planets going together because of gravity.

The next force is the weak force also known as the weak interaction . What happens is let’s say we have a carbon 12 atom. It has 6 protons and neutrons in it’s nucleus. So what happens is one of it’s neutrons-essentially 3 of it’s quarks turning in to a proton turning the atom in to a nitrogen 12 atom. And it is going to emit electron and anti-electron neutrino. (I have no idea what a anti-electron neutrino is 😱).The weak force is 10 to the 25th TIMES the strength of gravity!! 😱

In this drawing I drew a helium 4 atom turning into a lithium 4 ion because of the weak force. The black dots are quarks. You need 3 quarks to make a neutron or a proton. And the arrows coming off from the neutron are just showing it turning into a a proton

The next force is the electromagnetic force. The electromagnetic force is why electrons don’t fly away from nucleuses. So there are two types of the electromagnetic force. So you know how sometimes when you have two magnets 🧲 and if you put them one way they will push away. And if you put them another way the stick together. Both of them are the electromagnetic force. Another two forces that are like the same force are the Coulomb force and the electrostatic force. This is what they do: if you have two things with the same charge they will also push away. And if you have two things that have the different charges they will stick together. And you might say why don’t the protons in a nucleus repell? The next force takes care of that. The electromagnetic force is 10 to the 36th TIMES the strength of gravity!!!! 😱

In this drawing I drew what the electromagnetic force, the electrostatic force and the Coulomb force do.

The next force is the strong force. The strong force is why the protons in a nucleus don’t fly away. Because if you get the protons close enough they will stick together. The strong force is 10 to the 38th TIMES the strength of gravity!!!!!!!! 😱

In this drawing I drew the strong force on a lithium 6 atom’s protons

I wrote this from memory from what I’ve learned in khan Academy
