Ptable renders them with WebGL from the quantum numbers using the Schrodinger equation, wrapping a threshold density of the generated point cloud with a surface. https://ptable.com/#Electrons/HOAO. - Source: Hacker News / 6 months ago
I was frustrated by the +4 oxidation state as well, but ptable.com says they exist based on the electrons tab. Probably only exists with fluorine, and maybe oxygen, at nonstandard temperature and pressures, but I honestly don't know. Source: about 1 year ago
Https://ptable.com/ is what I use in my Chem class. Works like a charm. Source: about 1 year ago
A useful resource can be found here: interactive periodic table At the top of the page click where it says “electrons.” Click on carbon, you can see its orbitals, as well as glean information regarding its electronic configuration. Source: over 1 year ago
There's been some updates PTable.com is a great resource. Source: over 1 year ago
The most correct answer is you have to do quantum calculations. In fact if you compare calculated vs empirical values on ptable.com, they differ a lot. There is a lot of math involved just to get an approximate answer so it's hard to distill all that in high school language. Source: over 1 year ago
Wikipedia is your friend when it comes to explaining the nature of the table itself. However, if you're looking for a good resource to reference the table itself, check out PTable. Source: over 1 year ago
Ptable is good. The Royal Society of Chemistry is good, but frankly, I prefer the RSC iPad (or phone) periodic table. Source: over 1 year ago
Some students need so much structure it's absurd. I am about a week away from taking away the trash cans in my one ICS class- it is a priviledge they are about to lose because five giant overgrown boys (high school) cannot manage to a) stay in their seat or b) resist throwing trash to 'make a basket'. I stare the gremlin who tosses the first throw down like death itself and promise that they get book work for a... Source: over 1 year ago
I think https://ptable.com/ has little figures of the MOs for the elements. Source: over 1 year ago
The other counterargument I see, that that information is not relevant in a professional context, is also true, but I don't think that is relevant for OPs question. They are learning now, and many of the periodic tables they will encounter include such information. The first non-Wikipedia site I find, https://ptable.com, includes physical state.

With both questions, I'd strongly recommend referencing a periodic table, such as one from ptable.com. Source: over 1 year ago
3) get yourself a good periodic table to reference that isn't the one in your book. It is a pain to keep flipping back and forth while doing homework. This is one of the best online ones: https://ptable.com. Source: over 1 year ago
We can actually get a pretty good idea from looking at the spectral emissions, at least which environments are likely to be more common. On ptable.com [0] you can compare the abundance of elements in a human to the abundance on Earth, meteors, the solar system, and the universe. It seems like despite an abundance of aluminum, silicon, iron, and titanium, relatively trace amounts are found in humans (a typical... - Source: Hacker News / almost 2 years ago

I use ptable.com and have found it way more interesting and helpful than cramming to learn every element by Tuesday for the test in high school. Source: over 2 years ago
There are 118 elements. Controlling them would be much more god-tier. Source: over 2 years ago

Ptable.com has them all pretty much covered: abundance, density, conductivity, melting points, boiling points, electron affinity, all kinds of radii, hardness, bulk modulus, year discovered, etc. Source: almost 3 years ago
