Kinda like Chemistry...

>What would a kilogramm of electrons look like?
Like a lot of empty space since electrons don't like sticking together

They would diffuse immidiately so you probably cannot see them

That's a fuckload of electrons m8

they will all be red and electricute you

An electron is not large enough to reflect visible light, they're too small and too high energy to be able to be clumped together like that, plus they require a nucleus around which to travel so they'd just go off flying through matter and space. Even if you could they are so impossibly small it would take an absurd amount of them which would create an insanely (unstable) negative force that would probably kill you and your entire family, which I'm inclined to think would be a net positive for humanity. It's an impossible scenario.

Suck my dick OP.

Op here again... Just wanna remind everyoneof the first sentence:

>For this thread we just despite the fact, that electronic charges would just rip this whole thing apart.

The charge and subsequent spin of electrons are the only real characteristics that define electrons. Thus, having a conversation about the sight and phase about the material would be about as useful as: How obese would a person have to be to break a chair, but independent of their weight.

>The charge and subsequent spin of electrons
What? Spin doesn't follow from charge. An electron neutrino is basically an electron with no electric charge - it still has spin 1/2.

I do not believe the electrons would display colour due to reflection of light and the "kg of electrons" would undergo coulomb fission and disappear. The closest thing you'll get to seeing electrons is in a spark or a solution of solvated electrons which give a nice blue colour

Given you'd need to put them in some kind of potential well to stop them from all fucking off, it wouldn't be transparent.
It would be an opaque, high pressure gas(ish) that glows by emitting black body radiation. The colour would vary based on how hot it was. The density would simply depend on how many electrons you put in the container, and how large the container was.

Literally just metal
There's a chemistry experiment I've heard of in which you get a bunch of pure electrons (can't remember what it's called) but it looks exactly like metal
