What is quantum entanglement?
What is quantum field and how many sub atomic particles are there?

Answer:
Quantum entanglement is a physical phenomenon that occurs when a pair or group of particles are generated, interact, or share spatial proximity in a way such that the quantum state of each particle of ...
In the physical sciences, subatomic particles are smaller than atoms.[1] They can be composite particles, such as the neutron and proton; or elementary particles, which according to the standard model are not made of other particles.[2] Particle physics and nuclear physics study these particles and how they interact.[3] The concept of a subatomic particle was refined when experiments showed that light could behave like a stream of particles (called photons) as well as exhibiting wave-like properties. This led to the concept of wave–particle duality to reflect that quantum-scale particles behave like both particles and waves (they are sometimes described as wavicles to reflect this[citation needed]). Another concept, the uncertainty principle, states that some of their properties taken together, such as their simultaneous position and momentum, cannot be measured exactly.[4] The wave–particle duality has been shown to apply not only to photons but to more massive particles as well.[5]
