Amos is using three different colors of candy to create atomic models. He constructs a model of an oxygen atom as demonstrated.

Question

8 Protons = red candy
10 neutrons = green candy
10 electrons = blue candy
Amos wants to modify this model to represent a different isotope of oxygen. What adjustments could he make to achieve this?

add one red candy

Answer 1

To modify his model to represent a different isotope of oxygen, Amos needs to change the number of neutrons while keeping the number of protons the same since isotopes of an element have the same number of protons but a different number of neutrons.

In this case, to represent a different isotope of oxygen, he could:

add one green candy

This would increase the number of neutrons and create a new isotope while keeping the 8 protons (red candies) and 10 electrons (blue candies) the same.
