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 ...
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...
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...
Step-by-Step Text Solution:Step 1: Define Isotopes Isotopes are atoms of the same element that have the same atomic number but different mass numbers. The atomic number (Z) represents the number of protons in t
A. Atomic number B. Mass number C. Electron configuration D. Chemical properties 相关知识点: 试题来源: 解析 B。同位素之间的主要区别在于质量数。原子序数决定元素种类,同位素的原子序数相同,所以 A 选项错误。电子构型在同位素中基本相同,C 选项错误。同位素的化学性质相似,D 选项错误。质量数等于质子数加中...
Mass number, in nuclear physics, the sum of the numbers of protons and neutrons present in the nucleus of an atom. The mass number is commonly cited in distinguishing among the isotopes of an element, all of which have the same atomic number (number of p
The meaning of ISOTOPE is any of two or more species of atoms of a chemical element with the same atomic number and nearly identical chemical behavior but with differing atomic mass or mass number and different physical properties. How to use isotope in
One of two or more atoms having the same atomic number but different mass numbers. Isomers (Chemistry) Any of two or more substances that have the same molecular formula but differ in the way their atoms are connected to each other, in the spatial orientation of their atoms, or, in the ...
Most elements exist in two or more forms, known as isotopes. Isotopes have the same number of protons but differ in their number of neutrons, resulting in different masses. The lighter form is generally the more common one (Hobson & Wassenaar 2008). This variation in the relative abundance ...
