The table shows the electronic structures of atoms of five elements, P, Q, R, S and T.
The letters are not the chemical symbols of the elements.
| Element | Electronic structure |
|---|---|
| P | 2.8.2 |
| Q | 2.8.4 |
| R | 2.8.7 |
| S | 2.8.8 |
| T | 2.7 |
Which two elements are in the same group of the Periodic Table?
Element S does not react with other elements.
Explain why. Use its electronic structure.
Element P is a metal and element R is a non-metal.
Explain how their electronic structures relate to this difference.
Element P reacts with element R to make an ionic compound.
Deduce the formula of this compound. Use the letters P and R.
Explain your answer.
Element Q usually forms covalent bonds and does not form ions.
Suggest why.
Element T has the atomic number 9.
Explain how the electronic structure of T shows its position in the Periodic Table.
