Name the compound NO2. Since there is only one nitrogen atom AND it is the first element the prefix mono is not used. Add the ide ending to get oxide. There are two oxygen atoms so we also add the prefix di to get dioxide.
Example Problems Predict the formula and charge for: Sulfate comes from sulfur which is in the center box of the nonmetals so it have four oxygens. The root comes from phosphrous which is in the center box of nonmetals so it must have four oxygen atoms.
Phosphrous is three columns away from the right-hand side so its charge is Therefore, phosphate is PO Bromate must be BrO3—. How would you name the following: Iodine is outside the center box, so it must have three oxygen atoms. Iodine is in the first column from the right-hand side so the charge on the polyatomic must be 1- or just.
Therefore, iodate must be IO3—.
AsO — Arsenate would be AsO and this has two fewer oxygen atoms. SeO32— — Selenate is SeO What would hydrogen sulfate be? So hydrogen sulfate would be HSO4—. Selenium is two columns away from the noble gases so it needs two electrons, meaning selenide is Se How would you name: The charge becomes 2- because I removed a positive hydrogen ion.
I know that arsenate is AsO and this has one less oxygen atom, so it must be aresnite.Practice naming ionic compounds when given the formula Chemistry Atoms, compounds, Naming ions and ionic compounds. Naming monatomic ions and ionic compounds.

Finding formula for ionic compounds. CHEMISTRY Naming Compounds Handout page 1 of 12 IONIC COMPOUNDS versus MOLECULAR COMPOUNDS ionic compound: consist of cations (positive ions) and anions (negative ions) held together by electrostatic attraction –usually metal + nonmetal(s) WRITING CHEMICAL FORMULAS GIVEN INDIVIDUAL IONS.
Practice finding the formula when given the name of an ionic compound. Here is a collection of study cards for my AP and General Chemistry classes.
There are four cards per page. Each set of cards is saved as an Adobe Acrobat® file. Oxygen is the first element in Group 16 (VIA) of the periodic table. The periodic table is a chart that shows how chemical elements are related to each other.
