▲Bhí [[George Johnston Stoney]], fisicí [[Éireannach]], ar na chéad daoine a d’úsáid an focal ‘leictreon’ ar an gcainníocht bhunúsach luchta a fhaightear sa leictrealú<ref>Alex Keller: The Infancy of Atomic Physics. Hercules in His Cradle, Oxford University 1983. ISBN 0-19-853904-5</ref>.
Ba é Robert Millikan, [[Stáit Aontaithe Mheiriceá|Meiriceánach]], an chéad duine a rinne luach an luchta ar an leictreon a thomhas<ref>[http://www.rewardinglearning.org.uk/common/includes/microsite_doc_link.aspx?docid=2150-1 GCE Physics] A2 1 (Irish) Sum06.indd</ref>. D’úsáid sé [[turgnamh]] cáiliúil ar a dtugtar an turgnamh [[ola]]-bhraonach. Fuair sé amach go bhfuil lucht dar luach −1.6 × 10<sup>−19</sup>[[Cúlóm|C]] (nó an luach sin iolraithe faoi shlánuimhir éigin) ar bhraon ola a luchtaítear go leictreastatach.
