particle physics - What is the Weak force?

In this Particle Physics books I'm reading it explains Weak force with Beta Decay, a Neutron turns into a Proton after emitting an electron, so after it emits an electron one of the neutrons down-quarks turn in to an up-quark, and for this there needs to be a force, which is the Weak force. This interaction is carried by the W and Z bosons. Now, I asked someone what Weak Force is and they said that it's the interaction between Protons and Electrons(Electronegativity). I would like to know what exactly the relation between the Weak Force and Electronegativity is, and if my initial definition of the Weak Force is wrong, I would appreciate it if I were corrected.

Answer

The "forces" used in current Standard Model of physics (the quotes are on purpose since there are other forces as well, in different context), are:

1. 
   
   

   "Strong Nuclear Force", in essence keeps the nuclei together, nuclear fission is based on this

   
   


2. 
   

   "Weak Nuclear force", in essence is a type of nuclear force (associated with nuclei) but has a smaller coupling constant, applies to intermediate distances than strong nuclear force and is involved in nuclei transformations like beta decay (coupling constant gives the relative measure of the force application to specific energy ranges, that is why the "weak" nuclear force, in contrast to "strong" nuclear force, one can see this as two facets of the same force acting in different energy ranges if one wishes to do so)

   
   


3. 
   

   "Electromagnetic force", in essense a force with applications in the distances and particles between weak nuclear force and gravity (see next). Most of everyday interactions are of electromagnetic nature. has a smaller coupling constant than nuclear forces.

   
   


4. 
   

   "Gravity force", well ypu know about this (hopefuly and the rest of us as well :))

   
   
   

In relation to weak force and electronegativity, this is not, in general, a ubiquitus conection or relation.

Weak force is invoved in many types of nuclear particle reactions (only some of which involve electrons), others involve muons or pions or other particles, so the connection with electrons and electronegativity is only partially standard.

However, what is standard (and is a basic result of physics referred to as Noether's theorem) is that in all these interactions, there are (generalised) charges (of which electric charge may be one) that are conserved. For example color is a type generalised charge that can be conserved in an interaction. So this the connection with charges (of which electric is one) that was the content of the question (and comment)
