- Atomic Number (Z): This is the number of protons in the nucleus of an atom. For isotopes of the same element, this number remains constant. - Mass Number (A): This is the total number of protons and neutrons i
Isotopes are atoms of an element that contain different number of neutrons in their atomic nucleus. They have the same atomic number, i.e., same number of protons (of course an equal number of electrons), but differ in their atomic mass due to the neutron numbers. For example, the three...
Samples of natural selenium contain six stable isotopes. these isotopes have the same number of proton & electrons in each atom they differ in the number of neutrons in each atom, the atomic mass, & their nuclear stability Electron configuration 1S2, 2S2, 2P6, 3s2, 3p6, 4s2, 3d10, 4p...
Elements in nature come in forms called isotopes that differ only in the number of their neutrons. Most isotopes are stable and can be distinguished from their counterparts simply by their masses. Remarkably, isotopes are associated with a few simple and mass-dependent traits that result in a wi...
By measuring the proportion of heavier hydrogen and oxygenisotopesalong a strand of hair, scientists can construct a geographic timeline. 通过测量一束头发上较重的氢和氧同位素的比例,科学家可以构建一个地理时间轴。 All theisotopesof a given element have the same number of protons, but differ in th...
Because each element is distinctive of its atomic number, all atoms of a particular element must have the same number of proton. The atomic number of carbon is 6. Then all kinds of carbon atoms must have 6 protons in their nuclei. So these atoms...

1). What they have in common is the proliferation of porphyry deposits, but they differ in lower crust lithology which includes granulite, hornblendite, and gabbro. Using geochemical and isotopic results, we investigate the Cu budget and isotopic composition of the lower continental crust and ...
the δ18Ootolithvalues of the temperateA. japonicawere higher than those of the tropicalAnguilla marmorata, recruited at the same locations in southern Japan and Taiwan. This suggests that larval migratory behavior in the ocean may differ between the two eel species, although they have sympatric ...
