1.	Which of the following is a stable nucleus?(a) The nucleus with even protons and odd electrons(b) The nucleus with even number of protons and neutrons(c) The nucleus with even neutrons and odd protons(d) The nucleus with odd protons and neutronsThe question was posed to me in an internship interview.The doubt is from Size of the Nucleus in chapter Nucleus of Physics – Class 12
Answer» Correct option is (b) The NUCLEUS with even number of protons and neutrons For explanation: The nuclei of atoms having even NUMBERS of both protons and neutrons are the most stable ones and this ALSO means that they are less radioactive than NUCLIDES containing even numbers of protons and ODD numbers of neutrons.
