Here is one yo have probably heard.  Magnets.

It would obviously attract and push metal filings.

If sparks pass through a conductor near the magnet, pressure is generated.

Magnetic fields will be generated when sparks pass through a conductor, except water and mercury.

Iron will become magnet the longer it is touching/near a magnet.

here is one 

This is an element i would like to see

Thanks

add LGOO (liquid goo)

STRN - (Short or Static Tron) - Essentially tron that doesn't grow (for races and because why not.)

EDIT: Not static in the sense that it doesn't move, but static in the sense that it moves but doesn't grow.

u shuldmake it to were u can delet someones save thats annouing u or a element called nuke wee its the most explosive thing in da hole game explodes withe nuetrones

TROL (troll) white & black solid that melts every element. lol

I sugest new group of elements. I like Standard Model. In group there are all particles.

Quarks     (u up, d down, s strange, c charm, t top, b bottom) [QARK]

Leptons    (electrons [ELEC], mions [MION], taons [TAON], neutrinos [NRIO] )

Bozons     (Photons [PHOT], Gravitons [GRVT], Wuons [WUON], Zetons [ZTON], Higgsons [HIGS], Boson X [BOSX], Aksions [AKSN], and my teory Dimensions [DIMN], Foltrons [FOLT] - matter-antimatter)

Hadrons    BARIONS and MESONS  Protons [PROT], Neutrons [NEUT], Delta [DELT], Pentaquark [PENT], Pions [PION], Kaons [KAON]

Dark matter     (very bizarre particles created colones and products nevtonian gravity about force)

Exotic matter no EXOT the matter is created 0,00000000000000000000000000000000001 second past big bang
