Chemistry-Chapter 5- Section 5.3

1. 1[blank_start]Electron[blank_end] [blank_start]configuration[blank_end] is the arrangement of electrons in an atom of an element in its ground state.

   1. AElectron
   2. Bconfiguration
2. 2In the [blank_start]Aufbau[blank_end] Principle, electrons must fill the [blank_start]lowest[blank_end] available energy sublevels before any can be placed in higher-energy sublevels.

   1. AAufbau
   2. Blowest
3. 3Electron configuration is written as the [blank_start]coefficient[blank_end], [blank_start]letter[blank_end], [blank_start]superscript[blank_end].

   1. Acoefficient
   2. Bletter
   3. Csuperscript
4. 4[blank_start]Orbital[blank_end] notation has one blank to represent each orbital. Each electron in the orbital is written as an [blank_start]arrow[blank_end] (up or down) above the blank of its orbital.

   1. AOrbital
   2. Barrow
5. 5Chemists often write the [blank_start]symbol[blank_end] of the element that fills the [blank_start]previous[blank_end] energy level in brackets before adding the next subelevels- this is called [blank_start]noble[blank_end] [blank_start]gas[blank_end] notation.

   1. Asymbol
   2. Bprevious
   3. Cnoble
   4. Dgas
6. 6The [blank_start]Pauli[blank_end] [blank_start]exclusion[blank_end] principle says that electrons must have [blank_start]opposite[blank_end] spins when they occupy the same orbital.

   1. APauli
   2. Bexclusion
   3. Copposite
7. 7[blank_start]Hund[blank_end]'s rule says as electrons fill a sublevel, all orbitals receive one electron with the [blank_start]same[blank_end] spin before the electrons begin to pair up. A sublevel's [blank_start]lowest[blank_end] energy state occurs when the sublevel has the highest possible number of [blank_start]electrons[blank_end] that have the same spin and are [blank_start]unpaired[blank_end].

   1. AHund
   2. Bsame
   3. Clowest
   4. Delectrons
   5. Eunpaired
8. 8 [blank_start]Valence[blank_end] electrons reside in the [blank_start]outermost[blank_end] energy level, are the most likely to be involved in chemical [blank_start]bonding[blank_end], and give elements many of their [blank_start]physical[blank_end] and [blank_start]chemical[blank_end] properties.

   1. AValence
   2. Boutermost
   3. Cbonding
   4. Dphysical
   5. Echemical
9. 9An [blank_start]ion[blank_end] is an atom that has [blank_start]lost[blank_end] or gained electrons and is no longer [blank_start]neutral[blank_end] (it has a net electrical charge).

   1. Aion
   2. Blost
   3. Cneutral
10. 10[blank_start]Cations[blank_end] are ions with a net positive charge. Anions are ions with a net [blank_start]negative[blank_end] charge.

    1. ACations
    2. Bnegative
