Atomic Structure
What is an atom?
The smallest unit of an element

The ability to cause change
What is the largest source of energy for the earth (99%)?
The sun
What can x-ray energy do?
It can go (see) through solid objects
What happens to the star in the protostar stage
The star begins to glow and the temperature starts to rise due to friction

What is an isotope
It is different forms of an element that have different numbers of neutrons in the nucleus
