According to a rule in geometry, the dimension of an object made up of n dimensions is n+1. For example a cube is 3d which is made up of squares which are 2d and a square is made up line segments which are 1d. So, as circle is made up of diameters which are 1d, it is 2d or second dimensional space. Hope you like it.
From the given, we have 232 90Th. Thorium has 90 protons in its nucleus, the number of neutrons is calculated by subtracting 90 from 232 which gives an answer of 142. Then, for the second given 228 88Ra, Radium has 88 protons and the number of its neutrons is calculated by subtracting 88 from 228 which is equal to 140.
The final equation that would give us the proper nuclear decay reaction,
232 90Th --> 228 88Ra + 4 2a
where 4 2a is an alpha particle.
