Define ionic and molecular (covalent) compounds. Predict the type of compound formed from elements based on their location within the periodic table. Determine formulas for simple ionic compounds. In ordinary chemical reactions, the nucleus of each atom (and thus the identity of the element) remains unchanged.

20 maj 2018 · Ionic compounds are named by stating the cation first, followed by the anion. Positive and negative charges must balance. Some anions have multiple forms and are named accordingly with the use of roman numerals in parentheses. Ternary compounds are composed of three or more elements.
The procedure for naming such compounds is outlined in Figure \ (\PageIndex {1}\) and uses the following steps: Figure \ (\PageIndex {1}\) Naming an Ionic Compound. Place the ions in their proper order: cation and then anion. Name the cation. Metals that form only one cation.
Binary ionic compounds are between a metal and nonmetal. This does not mean there are two atoms, but two types of atoms, so Al 2 S 3 is a binary ionic compound. The rules are simple, name the cation first and the anion second, giving the anion the -ide suffix. Cation (metal) first.
27 lip 2024 · If you're proficient in using formulae to represent chemical compounds but are not so confident in translating them into scientific names, our chemical name calculator may be just right for you. Here you will find the names and formulas of ionic compounds without having to memorize the terminology (or, at least, all of it).
The name of a binary compound containing monatomic ions consists of the name of the cation (the name of the metal) followed by the name of the anion (the name of the nonmetallic element with its ending replaced by the suffix –ide).
