Gold atoms contain large numbers of protons
WebThis isotope of technetium has 55 neutrons and 43 protons, giving a neutron-to-proton ratio of 1.28, which places 43 98 Tc near the edge of the band of stability. The atomic number, 55, is much less than the value of 83 above which all isotopes are unstable. These facts suggest that 43 98 Tc might be stable. WebAtoms are characterized by the number of protons found in their nuclei. The number of protons in the nucleus is referred to as the atomic number, and this number identifies the element. For example, all atoms with six protons are carbon (C) atoms, and all atoms with 79 protons are gold (Au) atoms. U Different elements have different atomic numbers.
