Use the periodic table to find the two ions (positive ion and negative ion) for each compound. Then write the formula. Remember, the overall charge of the compound is neutral (zero charge). Thus, the overall positive charge must be equal to the overall negative charge. Example: calcium chloride 2+ Ca C (These two charges are not the same, but 2 chloride ions will give an overali negative charge of -2. The positive ion already has a + 2 charge.) Ca²+ Cl₂ Therefore, CaCl₂ is the answer. Name 1) sodium chloride ex. 2) potassium bromide 3) calcium oxide 4) magnesium sulfide Ca²+ CI CI Positive Ion Na+ Count up the total charge. +2, -1, -1 This adds up to zero!! Negative Ion CI Formula NaCl K Br

I'm having trouble understanding how to put these formulas together

Worksheet 4: Writing Formulas for Ionic Compounds Use the periodic table to find the two ions (positive ion and negative ion) for each compound. Then write the formula. Example: calcium chloride CQ ²+ Remember, the overall charge of the compound is neutral (zero charge). Thus, the overall positive charge must be equal to the overall negative charge. 2+ Ca²+ Cl₂ Therefore, CaCl₂ is the answer. Name C (These two charges are not the same, but 2 chloride ions will give an overall negative charge of -2. The positive ion already has a + 2 charge.) 1) sodium chloride 2) potassium bromide 3) calcium oxide General Science 3200 4) magnesium sulfide 5) zinc chloride 6) sodium sulfide 7) strontium fluoride lithium oxide ex. 9) potassium nitride 10) sodium phosphide 11) aluminum chloride 12) calcium nitride 13) aluminum oxide 14) magnesium phosphide 15) aluminum sulfide Ca²+ CI CI Name: Joshua Smith Positive Ion Na+ Count up the total charge. +2, -1, -1 This adds up to zero!! Negative Ion CI- Formula NaCl K Br
