I was learning about this element recently, and it sparked a great idea in my head. I'm still confused about it to be honest, but there's a unique effect for it.

Element Name: SELE

Conductivity: Sparked only once, with photons.

The returning photons make a mark, on maybe wood. It has same imprint like where selenium was once before.

AIR WALL-

Stops air from passing, but allows particle to flow through.

I talked to Dnerd about it, and here is what I was thinking in the convo:

[03:04.25] <Dnerd> could you explain this idea to me?
[03:04.33] <Poorsoft> well..
[03:04.59] <Poorsoft> bombarding selenium with photons, returns photons with a ctype of SELE
[03:05.09] <Poorsoft> so: ELEC(SELE)
[03:05.09] <Dnerd> alright
[03:05.13] <Dnerd> yeah
[03:05.28] <Poorsoft> it must hit WOOD, and it makes a mark.
[03:05.44] <Poorsoft> perhaps, gives the touched wood a life of.. 70
[03:05.47] <Dnerd> like it turns the wood into something?
[03:05.53] <Poorsoft> yeah, sort of.
[03:06.04] <Dnerd> or sets the wood ctype to sele
[03:06.07] <Poorsoft> Life 70 of wood, would make it.. black?

Perhaps photons with only the ctype of SELE will not burn the wood. Also, the photons would disappear.

 A use is a photocopying machine.

For the wall, I myself (and maybe many others) get annoyed when AIR passes through a wall, any wall.
