FINAL JEOPARDY QUESTION:
Dalton's Atomic Theory has 5 points.
One point is that all matter is made up of atoms. Another point is that atoms combine in small number ratios when forming compounds. A third point is that atoms of the same element have the same mass.
NAME THE LAST 2 POINTS!
*Atoms are indivisible and indestructible, and they cannot be created or destroyed!
*Atoms of different elements have different masses.
