# What is the correct formula of a compound that has ten oxygen atoms and four phosphorus atoms?

Jun 24, 2017

${\text{P"_4"O}}_{10}$

#### Explanation:

The number of atoms of each element in the compound is represented by subscripts following the symbol of each element.

Therefore, we can write a compound with color(red)(4 atoms of sfcolor(red)("phosphorus" and color(blue)(10 atoms of sfcolor(blue)("oxygen" as

$\textcolor{red}{{\text{P"_4)color(blue)("O}}_{10}}$

($\text{P}$ is the symbol for phosphorus, and $\text{O}$ is the symbol for oxygen.)
