Answer:

10

Explanation:

Take a look to the chemical compound:

[tex]NaBO_3[/tex]

Which is Sodium perborate. Its chemical composition is:

[tex]Na=Sodium\\B=Boron\\O_3=Ozone[/tex]

In other words it has:

One sodium atom, one Boron atom and three oxygen atoms. Therefore, it has 5 elements in total.

However, as you can see the chemical compound has a coefficient of 2, so basically the number of elements of the chemical compound is multiplied by 2:

[tex]2*5=10[/tex]

Hence, the number of elements in [tex]NaBO_3[/tex] is 10
