8. The number of protons in the nucleus of an element is called its atomic number.

9. If two or more compounds are composed of elements A and B, the ratio of the masses of B combined with 1 g of A is always a ratio of small whole numbers. This is a statement of the law of definite proportions.

Hope I helped!
