Click on the Isotopes tab. Click on yellow cells in the periodic table shown in the upper right to select various isotopes.
Complete the following sentences about the subatomic particles contained in each isotope using the PhET simulation as a reference.
Part A. Match the words in the left column to the appropriate blanks in the sentences on the right. Make certain each sentence is complete before submitting your answer.
Although every element contains a unique number of protons, there can be atoms of the same element that contain a different amount of neutrons. These different atoms of the same element are referred to as isotopes and differ in their atomic mass. Click on the image below to explore this simulation, building your own isotope of a selected element or making a mixture of isotopes. When you click this simulation link, you may be asked whether to run, open, or save the file. Choose to run or open it
When the simulation is open you should the options to select Isotopes or Mixtures. Select Isotopes. You should see a scale with an atom of hydrogen on it. The current isotope (hydrogen-1) can be changed by adding neutrons from the bin located to the left of the scale. There is a periodic table in the upper right corner of the simulation showing cells in yellow representing the elements that can be selected. Clicking on the Mixtures tab at the bottom brings up a black background where custom isotope mixtures can be created or nature’s mix of isotopes can be viewed for a selected element.
