Whereas a state with two identical bosons of the same energy has an enhanced probability. This fairly simple bit of maths is responsible for the periodic table and the behaviour of all the elements.
Chemical elements consist of an atomic nucleus surrounded by electrons. Because electrons are fermions, not all the electrons can be sucked into the lowest energy level around the nucleus.
If they were, the probability of that "state" happening would be zero, by the argument above. So as more electrons are added around a nucleus, they have to sit in higher and higher energy levels - less and less tightly bound to the nucleus, in general. The behaviour of a chemical element - how it reacts with other elements and binds to form molecules, and where it sits in the periodic table - is driven by how tightly bound its outermost electrons really are.
When bosons clump together they do some fascinating stuff too, but it's hard to beat being responsible for the whole of chemistry, and therefore biology.

The standard model only consists of five elementary bosons. They are namely the Higgs boson, gluon, photon, Z and bosons. The Higgs boson have zero electric charge and zero spin is the only scalar boson. The last four bosons are known as gauge bosons or force carriers as they are responsible for fundamental interactions.
The gluon is responsible for the strong interaction that appears between particles made of quarks. Photon is the most familiar gauge boson and is responsible for electromagnetic interactions. Z and carry weak interaction. In addition, the mediating particle called graviton is responsible for the gravitational interaction. However, the standard model does not include the graviton.
The fundamental interactions associated with the gauge bosons are described by the gauge theory. The spins and electric charges of elementary bosons are shown in the following table.
The composite particles; mesons contain one quark and one antiquark , and nuclei of even mass number He- 4 are composite bosons. Moreover, bosons particles are not constrained by the Pauli Exclusion Principle, but fermions are. Apart from that, at the same quantum state, two boson particles can occupy at the same time, but fermions cannot occupy the same quantum state at the same time.
So, this is also a significant difference between bosons and fermions. Some examples for bosons include photons, gluons, helium atoms, etc. All the particles we know can be divided into two groups as bosons and fermions, based on the spin of particles. The key difference between bosons and fermions is that bosons have integer spin, whereas fermions have a half-integer spin.
