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...

All theisotopesof a given element have the same number of protons, but differ in their number of neutrons, and hence in their atomic mass. 给定元素的所有同位素都含有相同的质子数,但它们的中子数不同,因此它们的原子质量也不同。 Heavierisotopestend to be left behind when water evaporates from the...
Isotopes are variants of a particular chemical element which differ in neutron number, although all isotopes of a given element have the same number of protons in each atom. The term isotope is formed from the Greek roots isos (ἴσος"equal") and topos (τόπος"place"), meani...
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...
For isotopes of the same element, this number remains constant. - Mass Number (A): This is the total number of protons and neutrons in the nucleus. Since isotopes differ in the number of neutrons, their mass numbers will differ. 3. Analyzing the Options: - Option A (Number of Protons)...
How can carbon isotopes reveal the presence or absence of ancient life on Earth?Radioactive Isotopes:Isotopes are atoms of an element that vary in the number of neutrons contained in their nucleus. Some isotopes are radioactive, which means that they are unstable and decay to f...
(b) How do the isotopes of a given element differ? Isotopes: These elements have similarities in atomic number but different masses because they have a different numbers of neutrons. Due to this, the atom's charge will not be affected, but some differen...
36S with the corresponding mass numbers (12 Da3 for 12C and 13.003354835 Da for 13C; Meija et al. 2016, IUPAC 2018) will result in an average atomic weight of 12.011 Da for the element carbon (IUPAC 2018).4 As mentioned above, isotopes of an element are either stable or radioactive....
Isotopes do not influence the basic chemical reactions of an element, as electron arrangements, governed by the number of protons, remain unchanged. Isomers can exhibit vastly different chemical behaviors due to their structural variations, affecting how they interact with other molecules. 6 In terms...
