Nonmetals stem name

Nearly all binary molecular compormds involve two nonmetals bonded together. Although many nonmetals can exhibit different oxidation numbers, their oxidation numbers are not properly indicated by Roman numerals or suffixes. Instead, elemental proportions in binary covalent compounds are indicated by using a prefix system for both elements. The Greek and Latin prefixes for one through ten are mono, di, tri, tetra, penta, hexa, hepta, octa, nona, and deca. The prefix mono- is omitted for both elements except in the common name for CO, carbon monoxide. We use the minimum number of prefixes needed to name a compound unambiguously. The final a in a prefix is omitted when the nonmetal stem begins with the letter o we write heptoxide, not heptaoxide. ... 

A ternary compound consists of three elements. Ternary acids (oxoacids) are compounds of hydrogen, oxygen, and (usually) a nonmetal. Nonmetals that exhibit more than one oxidation state form more than one ternary acid. These ternary acids differ in the number of oxygen atoms they contain. The suffixes -ous and -ic following the stem name of the central element indicate lower and higher oxidation states, respectively. One common ternary acid of each nonmetal is (somewhat arbitrarily) designated as the -ic acid. That is, it is named by putting the element stem before the -ic suffix. The common ternary -ic acids are shown in Table 4-16. It is important to learn the names and formulas of these acids, because the names of all other ternary acids and salts are derived from them. There are no common -ic ternary acids for the omitted nonmetals.

Two types of acids are named differently. Water solutions of binary covalent compounds containing hydrogen and a nonmetal are named following the pattern hydro(stem)ic acid, where (stem) is the stem of the name of the nonmetal bonded to hydrogen. Acids in which hydrogen is bonded to polyatomic ions have names based on the name of the polyatomic ion to which hydrogen is bonded. 

Monatomic anions are named by adding the suffix -ide to the stem of the name of the nonmetal from which they are derived. 

Binary compounds consist of two elements they may be either ionic or molecular. The rule is to name the more metallic element first and the less metallic element second. The less metallic element is named by adding an -ide suffix to the element s unambiguous stem. Stems for the nonmetals follow. 

Binary acids are compounds in which H is bonded to a Group VIA elemeut other than O or to a Group VILA element they act as acids when dissolved in water. The pure compounds are named as typical binary compounds. Their aqueous solutions are named by modifying the characteristic stem of the nonmetal with the prefix hydro- and the suffix -ic followed by the word acid. The stem for sulfur iu this iustauce is sulfur rather thau sulf. ... 

The binary acids are named by adding the prefix hydro- to the stem of the nonmetal followed by the -ic ending then adding the word acid. Hydrogen chloride, HC1, becomes hydro- chlor -ic acid, HCl(aq). 

The chemical name is composed of the name of the metal followed by the name of the nonmetal, which has been modified to an identifying stem plus the suffix -ide. 

For example, sodium chloride, NaCl, is composed of one atom each of sodium and chlorine. The name of the metal, sodium, is written first and is not modified. The second part of the name is derived from the nonmetal, chlorine, by using the stem chlor- and adding the ending -ide-, it is named chloride. The compound name is sodium chloride. 

To name a binary acid, place the prefix hydro- in front of, and the suffix -ic after, the stem of the nonmetal name. Then add the word acid ... 

These prefixes and the corresponding number of atoms that they represent are given in Table 3.3. Utilizing this scheme, CO would be named carbon monoxide and CO2 would be named carbon dioxide. Notice in these exan les that the element that is shown first in the formula is also named first. The second word uses the stem of the second nonmetal and the -ide ending, as in the scheme for ionic binary compounds. However, a prefix is placed in front of the stem to indicate the number of atoms of the second nonmetal in the formula (mono- in the case of one atom and di- in the case of two). Actually, a prefix is also used in front of the name of the first element if there is more than one atom of this element indicated in the formula.. For example, the compound N2O is called...
