Nuclear Composition and Nuclides Quiz

Nuclear binding energy = Energy required to disassemble a nucleus into its component parts Mass defect = Difference between the mass of an atom and the sum of the masses of its components Ground state = Most stable arrangement of nucleons within the nucleus Excited state = Unstable state with higher energies than ground state

Electrical forces of repulsion = Like charges repel, causing repulsion between protons Strong nuclear force = Force that operates only at small distances within the nucleus Metastable state = State that exists longer than excited states before transforming into ground state Binding energy per nucleon (EB/A) = Energy equivalent to the mass defect for a given nuclide

Transient existence (10E-12 s) = Characterizes excited states in nucleons Longer existence (>10E-12 s) = Characteristic of metastable states in nucleons Transformation into ground states = Common fate of both excited and metastable states Stability of ground state = Most stable arrangement of nucleons within the nucleus

<p>Mass number = Total number of protons and neutrons in the nucleus Atomic number = Number of protons in the nucleus Ionization potential = Energy required to remove an electron from its ground state Nucleons = Collective term for protons and neutrons in the nucleus</p> Signup and view all the answers

<p>Matter is anything that has mass and occupies space. = Definition of matter Electron Binding Energy is lowest when n = 1. = Property of electron binding energy Nucleus is composed of protons and neutrons. = Composition of atomic nucleus Mass of nucleons is significantly larger than electron mass. = Comparison of nucleon masses</p> Signup and view all the answers

<p>Atomic nucleus = Center of an atom where protons and neutrons are located Mass number = Total number of nucleons (protons and neutrons) in an atomic nucleus Ionization potential = Energy required to remove an electron from an atom's ground state Nucleons = Collective term for particles found in an atomic nucleus</p> Signup and view all the answers
