Question

Match the following elements with the correct location on the periodic table. (Not all elements can be placed!)
Period 4-group 2, Period 5-group 13, period 2-group 15, period 7-group 17.
The elements: calcium, tennessine, nitrogen, phosphorus, indium

Answer 1

Here are the matches for the elements and their corresponding locations on the periodic table:

1. **Period 4 - Group 2**: **Calcium (Ca)**
2. **Period 5 - Group 13**: **Indium (In)**
3. **Period 2 - Group 15**: **Nitrogen (N)** (Note: Phosphorus is actually in Period 3 - Group 15)
4. **Period 7 - Group 17**: **Tennessine (Ts)**

Phosphorus does not match any of the specified groups and periods.

So, the final matches are:
- Period 4 - Group 2: Calcium
- Period 5 - Group 13: Indium
- Period 2 - Group 15: Nitrogen
- Period 7 - Group 17: Tennessine
