Èlèktron
Elektron panèka partikel subatom sè bermuatan negatif sè biasana ètolès mènangka e -. Elektron ta' andi' komponèn otabâ substruktur dhâsar sè èkennal, bân polana jârèya èparcajâ mènangka partikel dhâsar.[1] Elektron aghâdhui massa ra-kèra 1/1836 dâri massa proton.[2] Momentum sudut intrinsik (spin) elektron panèka nilai satengnga bilangan bulat è dâlem satuan ħ, artèna panèka fermion. Antipartikel elektron èsebbhut positron, sè padâ sareng èlektron namong aghâdhui muatan positif. Manabi èlektron tabra'an sareng positron, bisa salèng berhamburan otabâ ancor sacara samporna, sè ngasèllaghi pasangan (otabâ lebbi) foton sinar gamma.
Elektron, sè tamaso' dâ' generasi pertama dâri keluarga partikel lepton,[3] noro' interaksi gravitasi, interaksi èlektromagnetik, bân interaksi lemah.[4] akadhi sadhâjâ materi, elektron andi' sifat partikel bân gelombang (dualitas gelombang-partikel), sè bisah atabra'an sareng partikel laèn bân èdifraksi akadhi cahaya. Polana elektron panèka fermion, tadâ' duwâ' èlektron sè bisa aghâdhui kabâdâ'an kuantum sè padâ metorot prinsip èksklusif Pauli.[3]
Konsep muatan listrik sè ta' bisa èbâgi èteoriaghi kaangghuy ajellassaghi sifat kimia atom sareng filsuf alam Richard Laming molaè taon 1838;[5] nyamana elektron èkennalaghi ghâbây muatan panèka è taon 1894 sareng fisikawan Irlandia George Johnstone Stoney. Elektron èkennal kalabân berhasil mènangka partikel è taon 1897 sareng J.J. Thomson.[6]
