3D Periodic Table: The first periodic table was developed in 1862 by a French geologist called Alexandre-Émile Béguyer de Chancourtois. He plotted the elements on a cylinder with a circumference of 16 units, and noted the resulting helix placed elements with similar p…
Chemists can’t agree on the best way to arrange the elements, prompting proposals of everything from spiral-shaped alternatives to radically elongated versions
I’ve always wondered what it would look like if each square’s area was proportional to the element’s abundance on Earth, or the Cosmos. I am linking to this as although it isn’t it, it does give it a modern day twist.
New periodic table focuses on sustainability, gaining a physics PhD age 89 – Physics World
This is cool, I made one at college once, and wished you could buy them as they are great. A magnetic one that you could assemble and disassemble would be a great gift too.
Introducing the Nuclear Periodic Table of Elements
How come there are articles and videos online that claim that electrons are subatomic particles – the web was invented decades after we realized they weren’t. Anyways, they are still our best little friends. Arvin does a good job of explaining them here.
Andrejs Skuja  asked the Naked Scientists:    Hi Chris, I have a query I’d love answered if possible. I was recently posed the question, ’Why do our s...
Don’t let the below commenters put you off. Angular momentum is just as real for quantum particles, you just have to quantize it first. I like your idea, so do many very highly respected physicists.
you sure? “When an electron moves from a higher orbital to a lower orbital, the atom emits a photon. … Angular momentum is conserved only if there’s no external forces, in this case the electron gains energy by light or by heat wich is kinetic energy.”
Is the conservation of angular momentum violated in electron jumps from one orbital to another?
I don’t really know any quantum mechanics. But in our class, we were introduced to Bohr’s model of the atom with his postulate that the angular momentum of an electron in the $n$-th orbit is $frac...
Hmmm, i can see how a simplistic view of conservation of energy indicates that “the closer you get, the faster you go” but I think the analogy ends there. Electrons don’t even actually orbit the center of atoms, that was just a way to explain it, way back. Sorry.

Every time we use our phones, tablets or laptops we are entering an invisible world of wireless digital signals. It is a world that we cannot see but that is literally all around us.

This would be amazing, but you would need to move a slider to tell it which frequency you want otherwise it would be a confusing mess. Watch this. I want one, someone should make the sensor and app.
Detect the electromagnetic fields near you, known as EMF. It's not necessary an expensive electronic equipment. Your device is already a sensor to detect EMFs.

Interesting, in the description he says “Most entanglement videos discuss the concept just using Bell States, which were first discussed by Einstein, Podolsky, and Rosen, in their paper on the EPR Paradox. These states are special cases that allow us to understand what an entangled quantum state is most easily, but they aren’t the general case. I wanted to discuss the general case here, and what it specifically means to have an entangled state.”
Bell Test debunked – they are not entangled – its not that seeing one glove makes the other’s wave function collapse, just that if this one is a right hand glove, then the other is known to be a left hand glove – no spooky action, no magic, get over it.
'Quantum Entanglement for Babies' is a colourful and simple introduction to one of nature's weirdest features. Entanglement has puzzled even the world's greatest scientists. Maybe with an early start, baby will be the first to understand it!
You can make this beautiful version at instructables.
zillions of options have been suggested. it likely won’t change though. Its; just wrong and likely will be forever. Just to confuse students.
This, but it looks like that “is it a rabbit or a duck” puzzle.
A more useful periodic table

Never heard of them before but they get a mention and an answer on Chegg.
Not sure about “bold” but electrons are still a long way from being understood, despite us using them all the time.
Angular momentum, in the form of “spin” is transferred to or from the photon. but read this to get a better idea of what you are trying to say… https://www.thenakedscientists.com/forum/index.php?topic=35361.0

looks like a particle to me. I think it is a particle and a wave. So do most that read physics.
What about this little beauty. Visualises the infosphere for you.
This would be amazing, but you would need to move a slider to tell it which frequency you want otherwise it would be a confusing mess. Watch this. I want one, someone should make the sensor and app.
This! But nothing on the app store that lets you point here and there to see whats going past, or through your brain. Ie microwaves, radio waves etc.
Thought I had found one online then but this thing just identifies the source of the radiation.
Yep, its the other way round. Visible light is just a tiny slither of the types of EM there is out there.
Wrong – Light is just one type of electromagnetism. Nice try, good idea though. heh
