The formula for the sulfate ion is SO 4 2-. The polyatomic ion is also just referred to as sulfate or sulphate. An ion is an atom or a collection of atoms that collectively have a positive or negative charge. They gain positive or negative charges by donating or accepting electrons.
The positive ion (cation) is written first in the name; the negative ion (anion) is written second in the name. Rule 2. When the formula unit contains two or more of the same polyatomic ion, that ion is written within parentheses and a subscript is written outside the parentheses to indicate the number of polyatomic ions.
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.

polyatomic ion itself. Recall that the positive ion is always written first in a compound including positive polyatomic ions. Name to Formula: A. Write the formula for sodium sulfate. Answer: Sodium ion is +1 and the sulfate ion is –2. You need two sodium ions for each sulfate ion. The formula is Na2SO4 B. Write the formula for barium hydroxide.
A polyatomic ion is charged and will form ionic bonds; for example, the sulfate ion SO42- forms many compounds, such as sodium sulfate. The bonds holding polyatomic ions together are covalent. ...
Ionic Compounds Ionic compounds are generally composed of a metal and a nonmetal or contain a polyatomic ion. More specifically, ionic compounds have an electronegativity difference of greater than 2.0. To convert from the name to the formula is a three-step process. Step one, look up and write down the symbols with their charges.
Writing Formulas & Names for Polyatomic Ionic Compounds / 2 Writing Formulas for Polyatomic Compounds The formula writing and naming of polyatomic ionic compounds is similar to the process for binary compounds. For example, making a compound using aluminum metal and nitrate yields: Al+3 NO 3-1 Al+3 NO 3-1 Al(NO 3) 3 Key Questions 1.
polyatomic ion itself. Recall that the positive ion is always written first in a compound including positive polyatomic ions. Name to Formula: A. Write the formula for sodium sulfate. Answer: Sodium ion is +1 and the sulfate ion is –2. You need two sodium ions for each sulfate ion. The formula is Na2SO4 B. Write the formula for barium hydroxide.
Jun 13, 2018· Na+ = Sodium Mg2+ = Magnesium Al3+ = Aluminum 2.Find the polyatomic ion on the Common Ion Table and write the name. Note: It is possible to have two polyatomic ions such as NH4NO3.
Jun 15, 2018· In this video we'll write the correct formula for Na2SO4 (Sodium sulfate). To write the formula for Na2SO4 we'll use the Periodic Table, a Common Ion Table, and follow some simple rules.
Aluminum is a metal and nitrate is a negatively charged polyatomic ion. In this lesson, we will discuss how to determine the formula for aluminum nitrate, what it is used for and its solubility.
Jan 08, 2017· Sulfate is a polyatomic ion with formula #(SO_4)^(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.
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
