Many of the common polyatomic ions have an electrical charge of -1. It's good to know these ions on sight to help balance equations and predict compound formation. acetate - C 2 H 3 O 2-. bicarbonate (or hydrogen carbonate) - HCO 3-. bisulfate (or hydrogen sulfate) - HSO 4-. hypochlorite - ClO -. chlorate - ClO 3-.
There are 3 ions in the formula Al2SO4 (2 aluminum and 1 sulfate), but this formula is wrong. The formula of aluminum sulfate is Al2(SO4)3 which contains 5 ions: 2 aluminum ions and 3 sulfate ions.
The mercurous ion is classified as a polyatomic ion. The following list shows names and symbols for some important polyatomic ions. As shown above, the symbol for the sulfate ion is: This indicates that one sulfur atom and four oxygen atoms are bonded together and that the whole polyatomic ion has two extra electrons.
Aluminium sulfate is an ionic compound, a combination of both positive and negative ions. Ions are charged atoms, which may either be monatomic ions (single atoms) or polyatomic (multiple atoms combined to form a charged part). Aluminium forms a + 3 ion, Al+3, and sulphate is the -2 polyatomic ion, (SO4)-2.
Table of common polyatomic cations, arranged by family. Alternate names are given in italics. Select the name of the ion for information about its occurrence, uses, properties, and structure. Blank entries are uncommon or unstable; for a complete table see the Field Guide to Polyatomic Ions.
Aluminum is a group IIIA element that forms ions with charge of while sulfate ion (polyatomic ion) has charge of. For the formation of electrically neutral aluminum sulfate compound, two and three ions are combined. Thus, the formula for aluminum sulfate will be. Hence, the correct answer will be option D.
Explanation: Sulfate is a polyatomic ion with formula (SO4)2−. Aluminum is a group 3A metal which forms a 3 + cation. A trick to balancing the charge is to use the number of the charge of one ion as the subscript on the other and vice versa. Al2(SO4)3. Answer link.
Aluminium sulfate is an ionic compound, a combination of both positive and negative ions. Ions are charged atoms, which may either be monatomic ions (single atoms) or polyatomic (multiple atoms combined to form a charged part). Aluminium forms a + 3 ion, Al+3, and sulphate is the -2 polyatomic ion…
The prefix poly- means many, so a polyatomic ion is an ion that contains more than one atom. This differentiates polyatomic ions from monatomic ions, which contain only one atom. Examples of monatomic ions include,,, and many, many others. This article assumes you have a knowledge of basic monatomic ions as well as the conventions for naming ...
Table of Polyatomic Ions There are a number of ions that are not individual atoms but are composed of multiple atoms that are covalently bonded together. However, this group of atoms is most stable when it has either lost of gained an electron and thus existed as a charged ion.
