Extract

Skābekļa atomiem savienojumos ar citiem atomiem oksidēšanās pakāpe VIENMĒR ir -2 (izņēmumus ir savienojumi ar fluoru un peroksīdi).
IA un IIA grupas elementiem oksidēšanās pakāpe sakrīt ar grupas numuru (piemēram, Ca- IIA grupas elements oks.pak. +2, K - IA grupas elements, oks.pak. +1).
Ūdeņraža atomiem savienojumos oksidēšanās pakāpe ir +1 (izņemot metālu hidrīdus).
Oksidēšanās pakāpe būtiski atšķirās no vērtības.
