8 Questions
Match the following terms with their corresponding definitions:
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
Match the following statements with the correct term:
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
Match the following timeframes with the correct state:
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
Match the following terms related to nuclear physics with their definitions:
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
Match the following particles with their properties:
Proton = Positively charged particle in the nucleus Neutron = Neutral particle in the nucleus Electron = Negatively charged particle orbiting the nucleus Nucleon = Term collectively referring to protons and neutrons
Match the following energy units with their significance in nuclear physics:
eV (electronvolt) = Unit used to measure binding energies of electrons in atoms Joule = Standard unit of energy in the International System of Units (SI) Binding energy = Energy required to hold together the nucleus of an atom Ionization potential = Energy needed to remove an electron from an atom
Match the following statements with the correct term:
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
Match the following concepts with their descriptions:
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
Test your knowledge on nuclear composition, mass number, neutron number, and nuclides' characteristics, including the arrangement of nucleons within the nucleus. Explore concepts related to the density of the nucleus and the difference between atomic weight, total number of protons, and neutron number.
