Explanation:

In this reaction, Sum of Atomic Masses of Left side = Sum of Atomic Masses of right side

Let the atomic mass of Thorium be x

So,

233 = 4 + x

Subtracting 4 to both sides

x = 233-4

x = 229

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
