How to do isotope notation? Isotopes: All atoms of a given element will contain the same number of protons. The number of protons in an atom of a given element is known as the atomic number (Z) of that element. However, the number of neutrons need not be the same in all the atoms...
The isotope with 29 protons and 35 neutrons is called copper-65. Chemists often write out isotopes using a notation involving the chemical symbol, atomic number, and mass number, as shown in Figure 4.16. Cu-65。同位素标记也可按图4.16中的方法表示。 Natural abundance of isotopes 同位素的自然丰度...
