Two-element compounds consist of two parts: a noun that indicates the type of chemical compound, is derived from the international name of the second sodium acetate element in the formula (a negative oxidation number), to which is added the ending -id (no matter sodium acetate oxidation number) of an adjective which is derived from an element with a positive oxidation number, the terminal indicates a value of oxidation number. endings of adjectives: -ný -natý -itý -ičitý -ičný / -ečný back slope -ista -ičelý What might interest you: oxygen in oxides has always -II oxidation number (the same is true for sulfur in sulfane, ... ) halogens (VIIA group) halide sodium acetate has always oxidation number -I hydrogen in hydrides sodium acetate oxidation number has always -I nitrogen nitride has always -III oxidation number of carbon in carbides has always oxidation number -IV Examples: carbon dioxide - C IV O 2 -II let us not forget that these numbers can be shortened, so instead of C 2 O 4 just write CO 2 figures, simply put, either cross-rule (2 to oxygen - after shorted), or calculate the numbers so that the net charge was zero oxygen-free sodium acetate acids consist graphics -vodíková acid + suffix to the name of the second element, which is herein occurs e.g. HCl - hydrochloric acid first element is written with a positive sodium acetate oxidation number, then negative
