Since isotopes differ in the number of neutrons, their mass numbers will differ. 3. Analyzing the Options: - Option A (Number of Protons): This is incorrect because isotopes have the same number of protons. - Option B (Valency Electrons): This is also incorrect as the number of valency ...
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...
1. Definition of Isotopes: Isotopes are variants of a particular chemical element that have the same number of protons (atomic number) but different numbers of neutrons. This results in different mass numbers for the isotopes of the same element. 2. Fundamental Particle of Difference: The fun...

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...
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...
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...
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...
Since isotopes have the same number of protons (same atomic number), they differ in the number of neutrons. 3. Example of Isotopes: - For the element carbon (C), there are three common isotopes: - Carbon-12 (C-12) with an atomic number of 6 and a mass number of 12. - Carbon-...
Isotopes are variations of elements with the same number of protons but different numbers of neutrons, affecting mass. Isomers have identical molecular formulas but differ in atom arrangements or bonds, influencing structure and properties. Difference Between Isotopes and Isomers ...
