28 Μαΐ 2024 · Write the chemical formula for the compound that is formed when aluminum and sulfur bond with one another. Solution. Based on the combinations listed in Section 3.2, these elements will combine to form an ionic compound, because aluminum, a metal, ionizes to form a cation (Al +3), and sulfur, a non-metal, ionizes to form an anion (S –2). The ...
28 Μαΐ 2024 · More accurately, Al 2 S 3 is the chemical formula for the ionic compound that is formed when the aluminum ion, Al +3, the cation formed when aluminum ionizes, and the sulfide ion, S –2, the anion formed upon the ionization of sulfur, bond with one another.
Name the following compound: Al 2 O 3. Answer. Aluminum oxide. Al is a Type I monatomic ion, no Roman Numeral is needed since the charge does not change. Change the oxygen ending to the -ide ending for the anion.
Aluminum and carbon react to form an ionic compound. Predict which forms an anion, which forms a cation, and the charges of each ion. Write the symbol for each ion and name them.
Predicting the Formula of an Ionic Compound. The gemstone sapphire (Figure 6.2c) is mostly a compound of aluminum and oxygen that contains aluminum cations, Al 3+, and oxygen anions, O 2−. What is the formula of this compound?
Learning Objectives. Write the chemical formula for a simple ionic compound. Recognize polyatomic ions in chemical formulas. We have already encountered some chemical formulas for simple ionic compounds. A chemical formula is a concise list of the elements in a compound and the ratios of these elements.
For example, what would the correct ionic formula be for aluminum sulfide? First, identify the two atoms involved (Aluminum and Sulfur) and start building your charge box with what you know from the periodic table.
