Subatomic Particles Video Lessons

Concept:

# Problem: Part D. In the PhET simulation window, click the green + symbols to expand the Mass Number tab. Drag protons, neutrons, and electrons from their respective bins onto the area above them and notice how this affects the information displayed in each tab. For extra conceptual practice, click on the Game menu and test your knowledge on any difficulty rating.Rank the atoms represented by the following sets of subatomic particles from smallest to largest in terms of mass.Rank from smallest mass to largest mass. To rank items as equivalent, overlap them. An atom is the smallest unit of matter that has the same characteristics of the element it represents. For example, you cannot divide a gold atom any further and still have gold. The building blocks for atoms have been discovered to be three different kinds of subatomic particles: protons, neutrons, and electrons. Different arrangements of these subatomic particles lead to the formation of atoms of different elements, charges, and mass.
