Reading chemical compound formulae

And chemical reaction equations

Цифра перед обозначением элемента указывает число молекул; 2MnO2, например, читается следующим образом: [´tu: ´mɔlɪkju:lz əv ´em´en´ou´tu:].

Знаки + и –, стоящие в левом верхнем углу, обозначают положительную и отрицательную валентность иона:

H+ – hydrogen ion [´haɪdrɪʤən ´aɪən] или univalent positive hydrogen ion [ˌju:nɪ´veɪlənt ´pɔzətɪv ´haɪdrɪʤən ´aɪən]

Cu++ – divalent positive cuprum ion [ˌdaɪ ´veɪlənt ´pɔzətɪv ´kju:prəm ´aɪən]

Al+++ – trivalent positive aluminium ion [ˌtraɪveɪlənt ´pɔzətɪv ˌælju´mɪnjəm ´aɪən]

Cl – negative chlorine ion [´negətɪv ´klɔ:ri:n ´aɪən] or negative univalent chlorine ion.

Знак — или : обозначает одну связь и не читается:
