Isotopes RAM Balancing Nuclear Equations 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. 79.90 u 78.91 u 78.34 u 80.00 u An alpha particle is a/an Proton Helium with a 2+ charge Helium atom Electron 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 Atomic Number or number of protons Mass number or number of protons and neutrons The number of electrons in an ion 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 letter ‘Z ‘represents, while using notations to write elements to represent the number of protons, neutrons and electrons is/are The number of electrons in an atom Atomic Number or number of protons Mass number or number of protons and neutrons Mass number or number of protons and electrons If the relative atomic mass of Br is 78.9183 what is its mass number 80 79 79.9183 78.9183 78 The number of neutrons in U-239 is 145 239 92 147 A beta particle is a/an Proton An ion with a negative charge Positron Electron Which among the following choices best describes an isotope? Elements that have the same number of neutrons but different number of protons 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 protons and neutrons Elements that have the same number of neutrons Isotopes of an element Shows both the same physical and chemical properties Show the same chemical property Not possible to predict Show the same physical property The number of neutrons in Pu-238 is 145 94 144 238 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 Loading … Question 1 of 12 Share this:TweetWhatsAppLike this:Like Loading...
