Oxidation state in compounds
Calculating an element's oxidation state in a compound or ion (sum = 0 or the ion's charge; O usually -2, alkali metals +1, Cl in chlorides -1, SO4 group -2) and naming with Roman numerals, e.g.
The idea, in English
Calculating an element's oxidation state in a compound or ion (sum = 0 or the ion's charge; O usually -2, alkali metals +1, Cl in chlorides -1, SO4 group -2) and naming with Roman numerals, e.g. iron(II), iron(III).
Explain in Egyptian Arabic
إزاي تحسب الـ oxidation state لعنصر في compound أو في ion: مجموع الـ oxidation states = صفر في الـ compound، أو = الـ charge بتاعة الـ ion. الـ O غالبًا -2، والـ alkali metals +1، والـ Cl في الـ chlorides -1، والـ SO4 group -2. وبعدها التسمية بالأرقام الرومانية، زي iron(II) و iron(III).
