Names and formulae of ionic compounds - BBC Bitesize
WebBecause sodium is a metal and we recognize the formula for the phosphate ion (see Table 3.1 "Some Polyatomic Ions" ), we know that this compound is ionic. However, polyatomic ions are held together by covalent bonds, so this compound contains both ionic and covalent bonds. WebIonic formula When you write the formula for an ionic compound, remember that the positive ion is always listed first. When there are two or more polyatomic ions in a formula, enclose the polyatomic ion in parentheses. Write down the information you have for the charges of the component ions and balance them to answer the problem. WebDescribe the difference between an atom and a molecule. Build simple molecules from atoms. Distinguish between the coefficient and subscript in a chemical formula. Construct molecules from the chemical formula. … photo editing special effects downloads
