In 1919, Rutherford bombarded the N2 with the ?-particles which are obtained from Ra - B (OR) Ra - C (Highly Energetic) and found that some new particles are produced. He analysed the particles and found that these are the protons. He proposed the reaction: $$\underset { Target }{ _{ 7 }^{ 14 }{ N } } + \underset { Projectile }{ _{ 2 }^{ 4 }{ He } } \longrightarrow \underset { Recoil \ target }{ _{ 8 }^{ 17 }{ O } } + \underset { Ejected \ particles }{ _{ 1 }^{ 1 }{ H } } $$This process in which atom of highly stable element (N) is converted into the atom of new element (O), artificially is known as atomic transmutation (OR) Artificial disintegration, and the reaction is known as Atomic transmutation reaction.
The following are the examples of atomic transmutation reactions: $$ _{ 13 }^{ 27 }{ Al } + _{ 2 }^{ 4 }{ He } \longrightarrow _{ 14 }^{ 30 }{ Si } + _{ 1 }^{ 1 }{ H } $$ $$ _{ 3 }^{ 6 }{ Li } + _{ 0 }^{ 1 }{ n } \longrightarrow _{ 1 }^{ 3 }{ H } + _{ 2 }^{ 4 }{ He } $$ $$ _{ 5 }^{ 10 }{ B } + _{ 0 }^{ 1 }{ n } \longrightarrow _{ 3 }^{ 7 }{ Li } + _{ 2 }^{ 4 }{ He } $$ $$ _{ 6 }^{ 12 }{ C } + _{ 1 }^{ 2 }{ D } \longrightarrow _{ 6 }^{ 13 }{ C } + _{ 1 }^{ 1 }{ H } $$ $$ _{ 1 }^{ 2 }{ D } + _{ 1 }^{ 2 }{ D } \longrightarrow _{ 1 }^{ 3 }{ T } + _{ 1 }^{ 1 }{ H } $$

Don’t want your columns to simply stack in some grid tiers? Use a combination of different classes for each tier as needed. See the example below for a better idea of how it all works.

For grids that are the same from the smallest of devices to the largest, use the .col and .col-* classes. Specify a numbered class when you need a particularly sized column; otherwise, feel free to stick to
