Isotopes Table Fill in Answer Key for Worksheet

Identify atomic number and mass number to classify each particle. The atomic number represents the number of protons, while the mass number is the sum of protons and neutrons. This distinction helps determine the element’s identity and its variants.

Determine neutron count by subtracting the atomic number from the mass number. The difference reveals how many neutrons are present, which can vary among different forms of the same element.

Compare different versions of the same element by observing their varying masses. Despite having the same atomic number, the difference in neutron count creates distinct atomic versions, affecting their stability and behavior.

This process is key to understanding how elements behave and react in different environments, aiding in various scientific applications, from medical imaging to energy production.
