What is a stable isotope? What isotope has 8 protons, 8 neutrons, and 8 electrons? What is the mass number of an isotope? What is the atomic mass of californium? What is the radioactive isotope of carbon? What do fluorine and chlorine have in common?
What is fermium's atomic mass number? What is the atomic mass of boron? What is the mass number of an isotope? What is curium's atomic mass number? What is the mass number of the uranium-238 atom? What is the mass number for krypton?
Can isotopes of the same element have different chemical properties? Generally, isotopes have identical chemical properties because they have the same electron configuration. 14 What defines an isotope? An isotope is defined by its number of neutrons, differing among atoms of the same element. 10 ...
The mass number of an atom is the total number of protons and neutrons contained within the nucleus of the atom. The number of protons determines the element and will always equal the atomic number of that element. The number of neutrons can change and will determine which isotope of that...
Definitions of an isotope: Isotopesare atoms of thesameelementthat have thesamenumber of protons butdifferentnumbers of neutrons. Another way to say the same thing is: Isotopesare atoms of thesameelementthat have thesameatomic number (whose symbol is 'Z') butdifferentmass numbers (whose symbol ...
1.To the correct number of significant figures,what is the mass of 2.5 moles deuterium gas(isotope mass=2.014 amu)?A.5.035gB.5.0g这个有效数字究竟是按2位算还是4位算?但是根据乘法有效数字的计算法则,不是应该是2位吗?2.A nearly equal volume of NaOH solution and acid are have been added....
Isotope and nuclide are closely related terms. When one speaks of isotopes, they are referring to the set of nuclides that have the same number of protons. Nuclide is a more general term, referring to a nuclear species that may or may not be isotopes of a single element. Examples: “U-...

The numbers you see here tell you the total number of protons plus neutrons in each atom. And they also tell you the isotopes approximate mass. Technically, the mass of an atom would include protons, neutrons, and electrons. But since the mass of an electron is almost 2,000 times less ...
Lithium has an atomic mass of 6.96. There are only two natural isotopes of Li: Li-6 and Li-7. What is the percent of each isotope present? Lithium has two naturally occurring isotopes, 6-Li and 7-Li, with masses of 6.015 amu and 7.016 amu...
