Question

How many calcium atoms in Ca(ClO3)2?

To make myself not sound dumb, I think the answer is 1 but I am asking to make sure I am right

Answer 1

1

Step-by-step explanation:

There is only one calcium atom because the subscript 3 applies only to the oxygen. Outside of the parentheses, the subscript 2 only applies to the chlorate ion. Therefore, there is only one calcium atom because there are no coefficients and subscripts. (Also drawing it out will help)
