Atomic orbitals are regions around the nucleus where the neutrons can be found. True False
Added by Nicholas B.
Step 1
Atomic orbitals are mathematical functions that describe the probability of finding an electron in a particular region around the nucleus of an atom. They are not physical regions where particles like neutrons can be found. Show more…

ATOMIC STRUCTURE 1. A neutral oxygen atom (atomic number = 8) has 8 electrons located in 2 different electron orbitals. True False 2. Hydrogen has only one neutron and no protons in its nucleus. True False 3. An atom consists of a central nucleus surrounded by electrons that are in constant motion. True False 4. Almost all of the mass of an atom is concentrated in its nucleus. True False 5. The orbital of an electron is the volume of space where the electron is most likely to be found. True False 6. Almost all of the volume of an atom is empty space. True False 7. The reactivity or chemical behavior of an atom depends primarily on the number of protons it has. True False 8. Modern physics indicates that we cannot determine the exact location of a particular electron at any given time. True False 9. Electrons are maintained in their orbitals by their attraction to the positively charged nucleus. True False 10. Atomic orbitals represent probability distributions for electrons and come in a variety of shapes. True False

Which statement about orbitals is false? Orbitals may contain up to two electrons each. Orbitals are regions of space where electrons are found. Orbitals are filled in order of decreasing energy. Orbitals of equivalent energy are half filled before adding two electrons to any one of them.
