A materials researcher records the atomic numbers of neutral atoms in two coded samples.
| Sample | Atomic number |
|---|---|
| M | 12 |
| N | 16 |
State the electron arrangement, group and period of sample M.
Suggest whether sample M is a metal or a non-metal and explain your answer.
Sample M and sample N are each reacted with an element of the opposite type. Compare how atoms of M and N are expected to behave in these reactions. Explain why.
