How are the isotopes of an element similar? a. atomic number b. atomic mass c. atomic mass number Atomic Number: The atomic number of an element represents the number of electrons or the number of protons in the element while the atomic mass represents the su...
In nature, most elements are found as mixtures of isotopes. Usually, no matter where a sample of an element is obtained, the relative abundance of each isotope is constant. 在自然界,大多数元素是多种同位素的混合。 通常,不同地区获得的元素中每种同位素的丰度是相同的。 For example, in a banana...
from Chapter 45/ Lesson 7 790K What are isotopes? Understand the meaning of isotopes with examples. Learn how to identify the isotopes. What are the types of isotopes and their properties? Related to this Question How do two different isotopes of carbon differ from each other?
The atomic mass for each element in the Periodic Table the mass is the average of the masses of the isotopes of the element weighed with their abundances. The atomic masses of isotopes are given in amu. Answer and Explanation:1 The percent abundance of isotopes can be calculated from the av...

Atoms of a particular chemical element often exist in slightly different forms called isotopes. The metal tin, for example, has ten stable isotopes: atoms that have the same number of protons and electrons (50 of each) but different numbers of neutrons. Stable isotopes are ones that are happy...
Nuclear bunker busters, like the B61-11, combine penetrating capabilities with nuclear explosive power, raising environmental, diplomatic and ethical concerns due to their immense destructive potential and the fallout they generate. There are thousands of military facilities around the world that defy co...
Isotopes of an element are specified by their mass number when written out. Thus the isotope of carbon with 6 protons and 6 neutrons is carbon-12, whereas the heavier isotope with one additional neutron is carbon-13. Most elements occur as a mixture of isotopes with one significantly predomin...
Certain elements are naturally radioactive in all of their isotopes. Uranium is the best example of such an element and is the heaviest naturally occurring radioactive element. There are eight other naturally radioactive elements: polonium, astatine, radon, francium, radium, actinium, thorium and ...
