When a metal object is heated what happens to its density? why?
What is It will decrease because the volume will increase
Explain what a saturated solution is.
What is a solution that can not hold anymore solute. It will not dissolve because there is not enough solvent.
explain how you find the number of protons, neutrons, and electrons
What
Protons - atomic number
