Chapter 3: Problem 70

Which of Dalton's principles is contradicted by a doctor using radioisotopes to trace chemicals in the body?

Short Answer

Expert verified
The principle of Dalton's theory contradicted by the doctor's use of radioisotopes is the principle that states atoms of the same element are identical in mass and other properties.

Step by step solution

01

Identify the Principle at Will

Recognize that Dalton's principle that can be possibly contradicted by using radioisotopes is the notion that atoms of an element are identical in mass and other properties.
02

Understand Radioisotopes

Secondly, grasp that radioisotopes are isotopes that have different masses but are of the same element. This indicates a contradiction because, according to Dalton's principles, atoms of the same element should possess the same characteristics, including mass.
03

Final Confirmation

Confirm that in the case of the doctor using radioisotopes for tracing chemicals in the body, it clearly contradicts the Dalton’s principle that atoms of the same element should have identical properties including mass. Therefore, it can be concluded that Dalton's principle contradicted here is the principle that atoms of the same element are identical in mass and other properties.
