What is the formula for Barium Chloride? Answer Barium is an alkaline earth and always corms a cation of charge of [+2], while chlorine is a halogen and always form the chloride ion of [-1].
12 Ιουλ 2023 · In the names of these oxoanions, the prefix per- is used to identify the oxoanion with the most oxygen (so that ClO 4− is perchlorate and ClO 3− is chlorate), and the prefix hypo- is used to identify the anion with the fewest oxygen (ClO 2− is chlorite and ClO − is hypochlorite).
If the metal can form ions with different charges, a Roman numeral in parentheses follows the name of the metal to specify its charge. Thus, FeCl 2 is iron(II) chloride and FeCl 3 is iron(III) chloride. Some compounds contain polyatomic ions; the names of common polyatomic ions should be memorized.
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.
The charge of the metal ion is determined from the formula of the compound and the charge of the anion. For example, consider binary ionic compounds of iron and chlorine. Iron typically exhibits a charge of either 2+ or 3+ (see Figure 2.29), and the two corresponding compound formulas are FeCl 2 and FeCl 3.
These can be simple ions such as the sodium (Na +) and chloride (Cl −) in sodium chloride, or polyatomic species such as the ammonium (NH 4 +) and carbonate (CO 3 2-) ions in ammonium carbonate. Individual ions within an ionic compound usually have multiple nearest neighbors, so are not considered to be part of individual molecules, but ...
3 Φεβ 2023 · < General Chemistry. ← Chemical Reactions · Formulas and Numbers →. Substances with carbon and hydrogen are organic compounds. They have special names that are beyond the scope of this book. For more information, see the Organic Chemistry Wikibook. Some compounds have common names, like water for H 2 O.
