We have seen that isotopes differ in mass number. The mass number has very little bearing on chemical reactions; therefore thereactivityand chemical reactions of an element's different isotopes are almost identical. The physical properties of atoms, however, do depend on mass. This enables isotopes...
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...
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...
Isotopes of Elements- Isotopes refer to elements with nuclei having the same number of protons, but differing numbers of neutrons, so that the masses of contrasting isotopes differ by one to a few neutrons. To learn more about the Types, Examples, Physic
Isotopes of a chemical element contain the same numbers of protons in their nucleus, but they have different numbers of neutrons. For example, the protium and deuterium isotopes of hydrogen both contain 1 proton, but differ by zero and 1 neutron respectively....
The combustion conditions differ when a cigarette is puffed compared to when it smolders, so the actual ratios of chemical constituents in sidestream and mainstream smoke also differ, although qualitatively the materials are similar. Because the temperature of the burning cone is lower as the cigar...
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 ...

Oxygen isotope ratios in mantle-derived magmas that differ from typical mantle values are generally attributed to crustal contamination, deeply subducted crustal material in the mantle source or primordial heterogeneities. Here we provide an alternative view for the origin of light oxygen-isotope signature...
KAC573 and sample KAC257/250 differ in their Paleoproterozoic zircon distribution, with distinct Eburnean vs K-N-E ratios. Samples 418/101, KAC236/237, and KAC573 display a predominance of Eburnean over K-N-E zircon, alongside significant proportions of early Siderian to Archean zircon (Fig...
