Term
|
Definition
When an electron moves from a higher level orbital to a lower level orbital, it emits (or gives off) light or energy. Remember: electrons is higher orbitals have more energy than electrons in lower level orbitals. |

Term
|
Definition
| a discrete unit of energy |
|
|
Term
|
Definition
| The orbital is where an atom keeps its electrons. An atom can have up to seven orbitals. We also call it a shell or energy level. |
|
|
Term
|
Definition
| Discrete energy states that an electron in orbit around an atom is allowed to have. Electrons may jump to a higher energy level by absorbing a photon or it can jump to a lower energy level by emitting a photon. |

|
Term
|
Definition
Region where electrons are found surrounding the nucleus OR The group of electrons revolving around the nucleus of an atom; a cloudlike group of electrons
|
|
|
Term
|
Definition
The assignments of electrons to particular principal quantum numbers and subshell designations in an atom.
OR A shorthand notation for describing the arrangement of the electrons around the nucleus. For example: Carbon's electron configuration is 1s2 2s2 2p2 |

Term
|
Definition
When an electron jumps from a lower level orbital to a higher level orbital, the electron is said to "absorb" the energy of a photon. Remember: electrons in higher level orbitals have more energy than electrons in lower level orbitals. |
