swansont Posted March 8, 2008 Share Posted March 8, 2008 What do you mean by net charge? The sum of the constituents. A neutron contains three quarks, whose charge adds to zero. The quarks each have charge. 1 Link to comment Share on other sites More sharing options...
Riogho Posted March 10, 2008 Share Posted March 10, 2008 The sum of the constituents. A neutron contains three quarks, whose charge adds to zero. The quarks each have charge. The neutron are made of two down quarks and one up quark. The down quarks have a charge of charge -1/3 and the up quark has a charge of +2/3 The charge units are the units of an electrons charge which is defined as one. As you know -1/3 + -1/3 + 2/3 is 0. In an antineutron the antidown quarks have an electric charge of +1/3 and the up quark has a charge of -2/3. Once more, equaling 0. Certain quantum numbers are also opposite, but I don't know enough about those to give you a good explanation so just take it as it is Link to comment Share on other sites More sharing options...
