Learning Intentions
- To show that you know how to create ionic compounds
- To show that you know how to name ionic compounds, and create their chemical formulas
Questions
- Choose 5 pairs of the following elements to create ionic compounds. You may not use the same element twice.
- Lithium, beryllium, boron, nitrogen, oxygen, fluorine, sodium, magnesium, aluminum, phosphorus, sulfur, chlorine, potassium, calcium, selenium, bromine, rubidium, strontium, iodine, cesium, barium, francium, radium
- For each pair, answer the following questions
- Which element will form the anion?
- What is the charge of the anion?
- Which element will form the cation?
- What is the charge of the cation?
- What is the chemical formula of the resulting compound?
- What is the chemical name of the resulting compound?
Assessment
- Accuracy (90%)
- Includes 5 pairs of atoms, using 10 different atoms
- Every pair includes an anion and a cation
- The questions are answered properly for every pair of elements
- Degree of difficulty (10%)
- There are no two pairs of elements where the anion and cation have the same charge
- Includes a pair where one element has a charge of +/- 3 and the other has a charge of +/- 2.
