WebNaming Acids with Polyatomic Ions The polyatomic ions you have memorized have –ate as the ending, so you name the polyatomic ion and change the ending to –ic . Use sulfate (SO 4 2-) as the example • H2SO 4 is sulfur ic acid • If the ion has one more oxygen atom than the base (SO 4 2-), then the ion is named by adding the Webtable. The cation name is formed by adding the word “ion” after the element name. For example, the element sodium (Na) is found in Group 1. It ionizes to form the “sodium … small town doctor movie

WebNote: The electron configurations in this worksheet assume that lanthanum (La) is the first element in the 4f block and that actinium (Ac) is the first element in the 5f block. If your … WebThe compound contains the complex ion [CuCl4] 2-and two Cs+ counter ions. The complex ion contains 4 ("tetra") Cl-ligands ("chlorido"). The complex ion is an anion so the ending "ate" is used. For copper, the "cuprate" is used. The oxidation number is +2 so the metal is cuprate(II). Hence, the complex ion is tetrachloridocuprate(II).
