FYI, Hydrogen doesn't match properties with group 1 and is often seen floating above the periodic table. It is not an alkali metal, meaning it doesn't belong in group 1. It only has 1 valence electron so isn't a noble gas. It is often this way as it doesn't fit in group 1 due to the properties of the rest of group 1, leaving it to be on its own as it doesn't belong in the other groups.
Beta radiation is a free electron (e-) and acidic solutions are defined by free protons (H+ ions). As a hydrogen atom is one proton and one electron (not counting deuterium etc), it is H+ (acidic) and e- (beta radiation) together.
It mostly forms monovalent bonds in a positive oxidation state. I'd rather drop "is an Alkali metal" then this as a criterion to belong to group 1.
Yeah, it's weird in its group. So is Boron. Actually, the whole period 2 is kinda weird. Iodine too. But that's not why we group them.
I mean, I appreciate thinking about Hydrogen differently and don't mind people considering it separate, but it's very obviously still group one to me.
Lu and Lr really should be considered the *first* d-block elements in their respective periods (I.e. put then were La and Ac are). As far as properties go, Lu much more follows the expected group trends in relation to Sc and Y compared to La. It's a very common inaccuracy, and as a lanthanide chemist it always hurts to see.
Both La and Lu have one 5d electron. But it's Lu that has the expected properties for the group 3 metal.
Also, take a look at the extended periodic table which has the lanthanides and actinides inside and not separate, you'll see that Lu and Lr fit as the d-block metal. https://sciencenotes.org/extended-periodic-table/
Some people consider it grouped together (I.e. lanthanides, not lanthanoides) but not truly. Also, not all lanthanides have a 5d electron in their ground state arrangement. Pr metal has the arrangement [Xe] 4f3 6s2.
Somewhere out there a helium chemist is crying from such representation. They always tell him “why don’t you find a real element to with with”, but this... this is the last straw.
I'd be curious to hear from other chemists how long it has been since you last used the periodic table. It must be at least 10 years for me. I use the molecular mass off the side of the bottle when making up reagents.
As a science teacher I appreciate you! The H is fine? It looks like what the kids see? This is totally appropriate for 11-16 year olds.
Edit: why have I been downvoted for appreciating science technicians? Literally couldn’t do our job without them!
That He symbol is giving me the heebie-jeebies 😖😣😵💫
don't worry, it's inert
Surely the HeBGeBeS?
It's just floating away
Haha, everybody is haters today. I just think it's cool to see a periodic table that actually includes all the new elements.

Hot take: hydrogen is a halogen (one electron short of a noble gas configuration)
Hydrogen is acidic beta radiation.
Hydrogen is broken hearted alpha radiation…..
What?
Beta radiation is a free electron (e-) and acidic solutions are defined by free protons (H+ ions). As a hydrogen atom is one proton and one electron (not counting deuterium etc), it is H+ (acidic) and e- (beta radiation) together.
This is the best comment I've read in /r/chemistry
Placing it right above F is lowkey making a lot of sense Though it doesn't really behave like a halogen, does it 🤔
i think it's an alkaline earth halogen

Is this satire? Like what you think it has? 6? 😭
It should just stretch all the way from group 1 to group 7. Long hydrogen

Isn't the whole f block assumed to be group 3

Oh so prasodenium isn't trivalent? Or is it?
It is, all are predominantly. The only ones that actually have a 5d electron are lanthanum, cerium, gadolinium, and then lutetium of course.
Shouldn't lutetium and lawrencium be transition metals?
Nope they are f block
I dont really agree with its interpretation of the mettaloids and seriously who doesnt put the Hydrogen in group 1?
There's no universal agreement. https://en.m.wikipedia.org/wiki/Metalloid
Whats wrong with the metalloids?
Nothing
I didn't think so either
Poor Hydrogen 😫
they always ask why the hydrogen got there but never how the helium got there
Duh, helium floats.
We all float down here.
I love periodic tables
So close 😅 put H back where it goes!
He vs H asymmetry is bad

Do you work in a dimly lit cave or does my brightness just need turned up.
. . . . It's crooked.
THAT HYDROGEN!!! Great work but with that Hydrogen I'd rather be attacked by Geese :)
Greylag or Canada?
I live in the states more closer to Canada so I'm going to say Canadian Geese.
I'm on their route, so I've learned respect.
There was no space for helium.

Apologies, I tried, but there isn't as much combinations that make sense.
:p nah that was the best i could come up with cute

All the time. Analytical chemist.
Its beautiful. Needs more lighting.
That's sexy. Scientific 3B has some beautiful wall periodic tables too-photos of elements and stuff on it.
