Also, to help understand this concept, there is a chart of the nuclides, known as a Segre chart. This chart shows a plot of the known nuclides as a function of their atomic and neutron numbers. It can be observed from the chart that there are more neutrons than protons<\/strong> in nuclides with Z greater<\/strong> than about 20 (Calcium). These extra neutrons<\/strong> are necessary for the stability of the heavier nuclei. The excess neutrons act somewhat like nuclear glue.<\/p>\n <\/a>See also: Live chart<\/a>\u00a0– iaea.org<\/a><\/p>\n Atomic nuclei consist of protons and neutrons, which attract each other through the nuclear force<\/strong>, while protons repel each other via the electric force<\/strong> due to their positive charge. These two forces compete, leading to various stability of nuclei. There are only certain combinations of neutrons and protons, which form stable nuclei<\/strong>.<\/p>\n <\/p>\n
