Chemical formulation 3 Ion groups

Ion groups E.g. Sodium hydroxide = NaOH Cation =Na+ Anion= OH- Anions made up of more than one element. They act like one atom E.g. Sodium hydroxide = NaOH Cation =Na+ Anion= OH- Calcium hydroxide Ca2+ OH- Ca2+ OH- OH- = Ca(OH)2

Ions that Contain Oxygen There are many atoms that form several different ions with oxygen. Memorize these ions! OH- = hydroxide   PO43-    = phosphate   SO42-    = sulfate   NO3-    = nitrate   ClO3-    = chlorate   CO32-   = carbonate CrO42-   = chromate

Ion groups practice NaOH Mg3(PO4)2 Fe2SO4 Ca(ClO3)2 AuPO4  Potassium hydroxide  Iron (II) sulfate  Beryllium nitrate  Silver (I) carbonate  Aluminium chromate

Ions that Contain Oxygen The naming system for these ions is based on two things: the most common ion in each series and the number of oxygen atoms compared to the most common ion. Memorize the most common ions! One more oxygen that the most common............... per____ate Most common............................................................... ____ate One less oxygen that the most common........................ ____ite Two less oxygens than the most common..............hypo____ite sulf SO52- sulf SO42- sulf SO32- sulf SO22-
