Isotopes同位素 Although an element contains only atoms with the same atomic number, these atoms, however, may have different mass numbers. For example, there are three different kinds of carbon atoms. One has a mass number of 12 and the other two re...
What does the number next to isotopes signify? The number indicatesthe isotope's mass number. 3. What is the number at the end of the isotopes name? Answer Expert Verified The number of protons and electrons remain same for two isotopes. This means isotopes have different mass number but ha...
The ratio of mass of.12Catom to that of an atom of element X(whose atomicity is four) is 1:9. the molecular mass of element X is: View Solution Isotopes are the atoms of same element, they have same atomic number but different mass numbers. Isotopes have different number of neutrons ...
And so all isotopes will have the same number, same atomic number, or the same number of protons. But once again, they do not have the same number of neutrons. So that means that they will have different mass numbers, which we're called the mass number is the total number of protons...

nAtoms of an element having different numbers of neutrons in their nuclei, and hence, different mass numbers. Isotopes of a given element have the same number of nuclear protons but differing numbers of neutrons. Naturally occurring chemical elements are usually mixtures of isotopes so that observed...
Isotopes have opened avenues for research in nuclear physics. 4 Allotropes A structurally differentiated form of an element that exhibits allotropy. Isotopes One of two or more atoms having the same atomic number but different mass numbers. Allotropes Plural of allotrope Isotopes Plural of isotope ...
Theory: Relative atomic masses measured by chemical methods rarely produce whole numbers but they should do (allowing for the low relative mass of the electron). This was explained when the mass spectrograph revealed thatatoms of the same element could have different masses due to the variation in...
Many of the elements on the periodic table have ‘isotopes’ that have the same chemical properties with different mass numbers. The different ratios of these isotopes can be measured in many of the chemical components that make up gases, oils, contaminants, and water. ...
Step-by-Step Solution:1. Definition of Isotopes: Isotopes are defined as atoms of the same element that have the same atomic number but different mass numbers. The atomic number represents the number of protons
