It's the periodic table of elements. It contains all the known atoms. Hope that clears it up for you.

All stuff is made of smaller stuff, let's call it stuffstuff. What you posted is a table of all the different types of stuffstuff that we know of. However, stuffstuff is made of even smaller stuffstuffstuff, which may be made of stuffstuffstuffstuff but we're not sure.
Hope I could help.

We know there exists something we call "electron." Electrons interact with each other via the electromagnetic force. Every neutral atom has at least one electron. Our current theories suggest that electrons are objects that have both wave-like and particle-like properties. There's also something called uncertainty; You can only know precisely about either position or momentum. Based on this, the electron of an atom could be anywhere in the universe, but it is most likely in the vicinity of the atom. We define an electron orbital as a space of the wave function, where there is a 90% chance of finding the electron when observing that space. Only two electrons with antiparallel spin (another electromagnetic property) can be in one orbital. Orbitals are filled up in specific structures we call electron configurations. Based on the electron configuration, we can predict the properties of atoms since all chemical interactions are mostly dependent it. We also have shells that repeat orbitals. A period is one shell. The first electron shell has only one "s orbital," filled with one electron. Two electrons occupy the s orbital of helium, making it a full shell that doesn't want to interact since the "goal" of the atoms is to have a full shell. This is also the reason why almost full/empty elements like alkaline metals or halogens are so violent when reacting with other elements. i.e. sodium wants to get rid of one electron to have a full first shell, while chlorine wants to snatch an electron away from it to have a full second shell. the result is an electron exchange where the positively charged electron donator (sodium) and the negatively charged electron acceptor (chlorine) are bound to each other via an ionic bond. Now you have table salt (sodiumchloride)

All the elements in the universe arranged by increasing atomic size (Number of protons). Columns are called "groups" and rows are called "periods".

It turns out the elements in any one "group" behave in a similar way physically and chemically e.g. Alkali metals (1st column) all react violently with water.
All elements in any one period (row) have the same number of electron shells (e.g. 1st row is 1s, 2nd row is 2p, 3rd row is 3p, 4th row is 4p and so on...)

Generally going from LEFT to RIGHT in a single row, the atomic radius decreases because more protons + same electron shell = increased pull, and going from TOP to BOTTOM in a single column the atomic radius increases because the atoms gain an electron shell despite the fact that there are more protons it is a competing effect, the outer electron has a more energy level.

Any questions?

>LEFT to RIGHT in a single row, the atomic radius decreases because more protons + same electron shell = increased pull
why does this outcompete electrons' charge-repulsion of each other, which should cause the atoms to get larger from left to right?

Atoms seek stability, if they feel ok as they are they won't want to associate with other nuclei

>> No.10535781

>>10535702
Because the added electron-electron repulsion is small compared to the added positive charge pull from +1 proton.

>> No.10535801

>>10535781
electron charge: -1
proton charge: +1
so how can it be relatively small?

Elements have protons, neutrons, and electrons. You get the next element by adding a proton. You get an isotope by changing the number of neutrons and you get an ion by adding or subtracting electrons.

>>10535277
a neat way of organizing atoms
turns out there's a correlation between the atoms in any single column as well as row
things like physical properties, reactivity, number of electrons are all connected there
colors are used to split the elements in to groups because the 1st column is VERY reactive with the second last column etc.
idk dude how do you not know this?

>> No.10536720

One of the most useful tools in chemistry. It's incredible once you realise how ones placement on the table relates to others, and its own characteristics.

I understand the electrons are physically ~1/2000 the size of the protons and neutrons, but we're talking about charge here. The electron and proton have equal and opposite charge despite their size difference, so I expect their attraction to cancel each other out in terms of shrinking or increasing the size of an atom. Aside from that, electrons occupy volume, as do larger nuclei, so why do they get smaller?
