Isotopes are atoms of the same element that have a different number of neutrons. They can be identified because they will also have a different mass number, or the mass of one atom of the element. Answer and Explanation:1 The mass number for carbon is 12amu. The mass number is the sum...
The mass number of an isotope refers to the number of protons and neutrons it contains in its nucleus. Each variation of an element's atoms will have a different mass number depending on the different numbers of neutrons. The number of protons cannot change without the atom becoming a differe...
The method uses a carbon compound as a raw material, and comprises reacting the carbon compound in the presence of hydrogen, a sulfur compound and a reaction catalyst at 500 to 1000 掳C, thereby producing 13 C .FUKUSHIMA HIDEOMIZUNO TADAHIKO...
