INFORMATION:
We have the next molecular compound
And we must name it
STEP BY STEP EXPLANATION:
To name binary (two-element) molecular compounds, we must 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 using a prefix
In our case,
the first element is Si: silicon and it has 3 atoms, so the first word of the name of the compound would be trisilicon.
the second element is N: nitrogen and it has 4 atoms, so the second word of the name of the compound using the suffix -ide would be tetranitride.
Finally, the name of the molecular compound is trisilicon tetranitride
ANSWER:
The name of the molecular compound Si3N4 is trisilicon tetranitride
