12 Ιουλ 2023 · By convention, however, when an inorganic compound contains both hydrogen and an element from groups 13–15, hydrogen is usually listed last in the formula. Examples are ammonia ( NH 3 ) and silane ( SiH 4 ).
25 Ιουλ 2022 · However, we will briefly discuss the important compounds known as oxyacids, compounds that contain hydrogen, oxygen, and at least one other element, and are bonded in such a way as to impart acidic properties to the compound (you will learn the details of this in a later chapter).
12 Ιουλ 2023 · The objective of this and the next two sections is to teach how to write the formula for a simple inorganic compound from its name—and vice versa—and introduce some frequently-encountered common names.
Naming Chemical Compounds - Answers. sodium bromide. calcium oxide. lithium sulfide. magnesium bromide.
The general formula for an acid is H n X, where X is an anion, H is a hydrogen ion, and n is the number of hydrogen ions needed to make the acid neutral. Binary acids are named by using the prefix hydro-, the root name of the anion, and the suffix -ic, plus the word acid.
H2O2 ...........................hydrogen peroxide. II. Molecular elements. The following should be memorized. All metallic elements are written in the singular (Fe, K, Dy, etc.) The inert gases (He, Ne, Ar, Kr, Xe, Rn) are also monatomic. However, some nonmetals naturally occur in groups.
1. The name contains two words. 2. Covalent compounds that contain hydrogen begin with hydrogen. Compounds that contain oxygen end in prefix-oxide. (This rule takes precedence over other rules below). 3. The first root word in the name is the name of the element that is in a column farther to the left in the periodic table. 4.
