Apr 27, 2023 · This formula indicates that a molecule of acetic acid (Figure 2.3.6 2.3. 6) contains two carbon atoms, four hydrogen atoms, and two oxygen atoms. The ratio of atoms is 2:4:2. Dividing by the lowest common denominator (2) gives the simplest, whole-number ratio of atoms, 1:2:1, so the empirical formula is CH 2 O.
Figure 3.4.1 3.4. 1: (a) A sodium atom (Na) has equal numbers of protons and electrons (11) and is uncharged. (b) A sodium cation (Na+) has lost an electron, so it has one more proton (11) than electrons (10), giving it an overall positive charge, signified by a superscripted plus sign.
Therefore, in this example, the base formula, Al 2 S 3, is the chemically-correct formula for the compound formed when aluminum and sulfur bond with one another. Exercise \(\PageIndex{1}\) Write the chemical formula for the compound that is formed when each of the following combinations of elements bond with one another.
Because the ionic compound must be electrically neutral, it must have the same number of positive and negative charges. Two aluminum ions, each with a charge of 3+, would give us six positive charges, and three oxide ions, each with a charge of 2−, would give us six negative charges. The formula would be Al 2 O 3.
Write a formula for the ionic compound that forms between each pair of elements. a. silver and chlorine b. sodium and sulfur c. aluminum and sulfur d. potassium and chlorine
Aluminum has an oxidation state of +3 or Al+3. Oxygen has an oxidation state of -2 or O−2. The common multiple of 2 and 3 is 6.? We will need 2 aluminum atoms to get a +6 charge and 3 oxygen atoms to get a -6 charge. When the charges are equal and opposite the atoms will bond as Al2O3. I hope this is helpful. SMARTERTEACHER?
