Isotopes RAM Balancing Nuclear Equations An alpha particle is a/an Electron Proton Helium with a 2+ charge Helium atom 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 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 True False 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 Mass number or number of protons and neutrons Mass number or number of protons and electrons The number of electrons in an atom The letter ‘A ‘represents while using notations to write elements to represent the number of protons, neutrons and electrons is/are Mass number or number of protons and electrons The number of electrons in an ion Atomic Number or number of protons Mass number or number of protons and neutrons 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 The number of neutrons in Pu-238 is 238 145 144 94 The number of neutrons in U-239 is 239 145 147 92 Which among the following choices best describes an isotope? Elements that have the same number of protons but different number of neutrons Elements that have the same number of protons and neutrons Elements that have the same number of electrons Elements that have the same number of neutrons Elements that have the same number of neutrons but different number of protons If the relative atomic mass of Br is 78.9183 what is its mass number 78.9183 79.9183 79 80 78 Determine the number of protons, neutrons, and electrons in the following isotopes: atomic number 9, mass number 18, charge of 1− Protons = 9 Neutrons = 18 Electrons = 9 Protons = 9 Neutrons = 9 Electrons = 10 Protons = 9 Neutrons = 9 Electrons = 7 Protons = 9 Neutrons = 9 Electrons = 9 A beta particle is a/an Proton An ion with a negative charge Electron Positron Loading … Question 1 of 12 Share this:TweetWhatsAppLike this:Like Loading...
