A computer analyses which atoms are joined by covalent bonds in two samples.
| Sample | Results of the analysis |
|---|---|
| P | The atoms form many separate bonded groups. Within each group, the same section occurs many times in a row. |
| Q | Starting from any atom, a path of covalent bonds can be followed to every other atom in the sample. |
A technician states that both samples have giant covalent structures because each sample contains a very large number of covalently bonded atoms.
Evaluate the technician's statement.
