Elements on the left hand side of the periodic table combine with elements on the right had side of the table to form ionic compounds. Examples are Li and
Br, Ca and Cl,etc. Elements in the middle of the table combine with elements on either side to form covalent compounds For example, CCl4 and CH4. Also, elements on the same side of the table (SO2, PCl3 etc) are covalent.
To match the elements and form ionic compounds, you need to consider the charges of each element and ensure that the charges balance out to form a neutral compound.
1. Determine the charges of each element:
- Cl: Chlorine typically has a charge of -1.
- Na: Sodium typically has a charge of +1.
- Mg: Magnesium typically has a charge of +2.
- O: Oxygen typically has a charge of -2.
- Be: Beryllium typically has a charge of +2.
- S: Sulfur typically has a charge of -2.
- Li: Lithium typically has a charge of +1.
- F: Fluorine typically has a charge of -1.
2. Identify the combinations that allow the charges to balance out:
- Cl (-1) can combine with Na (+1) to form NaCl, which is sodium chloride.
- Mg (+2) can combine with O (-2) to form MgO, which is magnesium oxide.
- Be (+2) can combine with S (-2) to form BeS, which is beryllium sulfide.
- Li (+1) can combine with F (-1) to form LiF, which is lithium fluoride.
Therefore, the matches to form ionic compounds are:
- NaCl (sodium chloride)
- MgO (magnesium oxide)
- BeS (beryllium sulfide)
- LiF (lithium fluoride)
