Parts Of An Atom | Properties of Matter | Chemistry | FuseSchool

Learn about the parts of an atom, their mass, and their charge, in this video.

We already know that atoms are really small but we can get smaller. If we zoom into an atom we find that is made up of protons, neutrons and electrons and a lot of empty space.

Imagine an Olympic swimming pool: 50 metres wide, this is our atom. At the centre of our atom is the nucleus. The nucleus is made up of protons and neutrons. But if we jumped into the pool to find the nucleus it would be pretty much impossible because it is a size of a grain of sand.

Around the nucleus you find that electrons are randomly whizzing around. The electrons are even smaller than protons and neutrons. So, say we only have two electrons in our atom. These would be randomly moving around our grain of sand in our 50 meter pool, just these two tiny, tiny electrons. So, what does that leave? a lot of empty space!

If we think about the minuscule scale that we're talking about, the constituents of an atom must have a minuscule scale to match. If we were to weigh protons, we would need 600 sextillion to just weigh one gram so one proton would have a very very small mass. The same is true for neutrons and electrons. This is why we weigh them in relation to each other.

We assign the mass of a proton as one. The neutron has a similar mass to protons and is also given the mass of one. The electron, however, is much lighter and has a mass of 1 over 1840. If we think about how heavy the mass of the protons and neutrons are in relation to the electrons it is clear to see that the mass of an atom is concentrated at the nucleus.

Protons, neutrons and electrons also have a charge associated with them. Protons are positive, neutrons are neutral and electrons are negative. The charge of an atom is always neutral. This means there must be the same amount of protons as there are electrons in an atom. The number of neutrons can vary and they do not affect the charge of the entire atom.

So I did a tad bit of research. In the video, the narrator claimed that a nucleus is the size of a grain of sand so it is super hard to see. Let me show you something. One atom is so small it is impossible to see with the naked eye, yet its the size of a grain of sand and you can see a grain with the naked eye. Let's get to the facts. There is about 43 QUINTILLION atoms in ONE grain of sand. even if the atom was 50 meters wide, it would not be one grain of sand.

After doing some extensive math they are still wrong:

one atom is about of a meter
one nucleus is about of a meter
meaning that a nucleus is of an atom

if we convert an atom to 50 m
then the nucleus would be of that
so
answer
a grain of sand is 2mm
and the nucleus would be .5 mm
so the video is off by 4
because a grain of sand would still be 4 times the nucleus
so they are still wrong :

And...

There we have it. I am finally getting science and geography videos in my reccomend. Thank you teachers.

P.s, really helps since I was doing atoms in science

pov: your teacher sent you this
tbh I really like science so I'm fine with this having in my recommendations

I don't think it's very beneficial to call the way electrons are moving "random" as their movement is not random at all and it will create a block in the mind as you head into more advanced chemistry. Simply stating that the electrons are moving around the nucleus is more true and still gives the picture of the electrons having multiple places they can be

at 1:12 it shows "600 sextillion" according to the narrator... but if you actually look at the number they typed, its 600 quintillion... mistake? this credible?

Great for my snail to do his exercise routine to. He said it was amazing

My online school kids where you at✋

good luck with ur studies✨

There is a thing wrong here you say that if you jump in the water and search for the atom you cannot see it because it is in the size of a sand well in fact it is indivisible
