Isotopes RAM Balancing Nuclear Equations 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 = 9 Protons = 9 Neutrons = 9 Electrons = 7 Protons = 9 Neutrons = 9 Electrons = 10 The number of neutrons in U-239 is 92 147 239 145 If the relative atomic mass of Br is 78.9183 what is its mass number 78 79.9183 80 79 78.9183 Isotopes of an element Show the same physical property Show the same chemical property Shows both the same physical and chemical properties Not possible to predict 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 neutrons Mass number or number of protons and electrons The number of electrons in an ion Atomic Number or number of protons 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. 80.00 u 79.90 u 78.34 u 78.91 u 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 electrons Mass number or number of protons and neutrons The number of electrons in an atom 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 The number of neutrons in Pu-238 is 145 144 238 94 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 electrons Elements that have the same number of neutrons but different number of protons Elements that have the same number of neutrons Elements that have the same number of protons and neutrons An alpha particle is a/an Helium atom Proton Electron Helium with a 2+ charge A beta particle is a/an Electron Positron An ion with a negative charge Proton Loading … Question 1 of 12 Share this:TweetWhatsAppLike this:Like Loading...
