Isotopes RAM Balancing Nuclear Equations A beta particle is a/an Positron Electron Proton An ion with a negative charge Which among the following choices best describes an isotope? Elements that have the same number of electrons Elements that have the same number of protons but different number of neutrons Elements that have the same number of neutrons Elements that have the same number of neutrons but different number of protons Elements that have the same number of protons and neutrons An alpha particle is a/an Proton Helium atom Electron Helium with a 2+ charge The number of neutrons in U-239 is 239 145 92 147 Isotopes of an element Show the same chemical property Shows both the same physical and chemical properties Not possible to predict Show the same physical property The number of neutrons in Pu-238 is 94 144 238 145 Determine the number of protons, neutrons, and electrons in the following isotopes: atomic number 9, mass number 18, charge of 1− Protons = 9 Neutrons = 9 Electrons = 10 Protons = 9 Neutrons = 9 Electrons = 9 Protons = 9 Neutrons = 9 Electrons = 7 Protons = 9 Neutrons = 18 Electrons = 9 The letter ‘Z ‘represents, while using notations to write elements to represent the number of protons, neutrons and electrons is/are Atomic Number or number of protons The number of electrons in an atom Mass number or number of protons and neutrons Mass number or number of protons and electrons The letter ‘A ‘represents while using notations to write elements to represent the number of protons, neutrons and electrons is/are The number of electrons in an ion Mass number or number of protons and electrons Mass number or number of protons and neutrons Atomic Number or number of protons If the relative atomic mass of Br is 78.9183 what is its mass number 79.9183 78 78.9183 79 80 When balancing nuclear reaction the following reasoning is used. Both the reactants and products the mass number should be same Both the reactants and products should have the same atomic number False True Bromine has two isotopes, Br-79 and Br-81, whose relative atomic are masses 78.9183 u and 80.9163 u and abundances are 50.69% and 49.31% Calculate the relative average atomic mass of Br based on these experimental results. 78.91 u 78.34 u 80.00 u 79.90 u Loading … Question 1 of 12 Share this:TweetWhatsAppLike this:Like Loading...
