This homeowrk assignment reviews atoms and ions including: ground state, excited state, Lewis dot diagram, Bohr models of ground and excited state, Heisenbrg Uncertainty Principle, Octet Rule, how atoms form ions
How are atoms in the ground state different from atoms in the excited state?
Drag the item to the appropriate category.
Use all items.
The number of energy levels matches the element's row # on the Periodic Table.
The atom could have extra energy levels.
Electrons release energy to attain this state.
All the electrons are in low energy levels and as close to the nucleus as they can get, in an organized and predictable pattern.
Electrons absorb energy to attain this state.
Electrons are in a variety of energy levels, and positions near the nucleus are empty.
Ground-State Atom
Which of the following could an atom, such as carbon, oxygen, sodium, or chlorine, do in order to adhere to the Octet Rule?
Select all valid options.
How is the number of valence electrons used to determine what an atom is most likely to do to form an ion?
