INFORMATION:
We have the next compound
[tex]P_4S_7[/tex]And we must name it.
STEP BY STEP EXPLANATION:
To name binary (two-element) molecular compounds, we need to know the following information:
The first element in the formula is simply listed using the name of the element. The second element is named by taking the stem of the element name and adding the suffix -ide.
We can use the following table to specify the number of atoms in a molecule
In our case,
the first element is P: Phosphorus and it has 4 atoms, so the first word for the name of the compound would be tetraphosphorus.
The second element is S: sulfur and it has 7 atoms, so the second word for the name of the compound adding the suffix would be heptasulphide.
Finally, the name would be tetraphosphorus heptasulphide.
ANSWER:
The name of compound P4S7 is tetraphosphorus heptasulphide
