Question: what is the exchange particle for strong nuclear force

title: Nuclear force
text: The discovery of the neutron in 1932 revealed that atomic nuclei were made of protons and neutrons , held together by an attractive force . By 1935 the nuclear force was conceived to be transmitted by particles called mesons . This theoretical development included a description of the Yukawa potential , an early example of a nuclear potential . Mesons , predicted by theory , were discovered experimentally in 1947 . By the 1970s , the quark model had been developed , by which the mesons and nucleons were viewed as composed of quarks and gluons . By this new model , the nuclear force , resulting from the exchange of mesons between neighboring nucleons , is a residual effect of the strong force . 

Answer: answer: The nuclear force, resulting from the exchange of mesons between neighboring nucleons, is a residual effect of the strong force.
