WebGenerally they are referred to by their mass number and the element name (which is the charge number). So for example, we could have \[\rm ^{197}_{\;79}Au\] This would be called "gold-197". It is gold (Au) since it has 79 protons (the charge number of 79) and it has 118 neutrons (197 - 79 = 118). \[\rm ^{195}_{\;79}Au\] Web16 de oct. de 2024 · Question From – Cengage BM Sharma OPTICS AND MODERN PHYSICS ATOMIC PHYSICS JEE Main, JEE Advanced, NEET, KVPY, AIIMS, CBSE, RBSE, UP, MP, BIHAR BOARDQUESTION... etanol előállítása
