Question

naming covalent compounds
name the following compounds:
chemical formula chemical name
$bf_{3}$
$si_{3}p_{4}$

Explanation:

Step1: Name $BF_3$

Prefix for 3 is "tri -", first element is boron and second is fluorine which becomes fluoride. So it's boron trifluoride.

Step2: Name $Si_3P_4$

Prefix for 3 is "tri -" and for 4 is "tetra -". First element is silicon and second is phosphorus which becomes phosphide. So it's trisilicon tetraphosphide.

Answer:

$BF_3$: boron trifluoride
$Si_3P_4$: trisilicon tetraphosphide
