Elements in the s - blocks Alkali metals all end in s1 Alkaline earth metals all end in s2 really should include He, but it fits better in a different spot, since He has the properties of the noble gases, and has a full outer level of electrons.

Transition Metals - d block Note the change in configuration. s1 d5 s1 d10 d1 d2 d3 d5 d6 d7 d8 d10

The P-block p1 p2 p3 p4 p6 p5

F - block f1 f5 f2 f3 f4 f6 f7 f8 f9 f10 f11 f12 f14 f13 Called the “inner transition elements” f1 f5 f2 f3 f4 f6 f7 f8 f9 f10 f11 f12 f14 f13

Each row (or period) is the energy level for s and p orbitals. 1 2 3 4 5 6 7 Period Number Each row (or period) is the energy level for s and p orbitals.

The “d” orbitals fill up in levels 1 less than the period number, so the first d is 3d even though it’s in row 4. 1 2 3 4 5 6 7 3d 4d 5d

f orbitals start filling at 4f, and are 2 less than the period number 1 2 3 4 5 6 7 4f 5f f orbitals start filling at 4f, and are 2 less than the period number

Shorthand Electron Configuration We can write the electron configuration of an element based off of the nearest noble gas (without passing or going beyond the element you are writing the E.C. for)

Shorthand Electron Configuration Be: F: Ne: K: Co: Te: [He] 2s2 [He] 2s2 2p5 [He] 2s2 2p6 [Ar] 4s1 [Ar] 4s2 3d7 [Kr] 5s2 4d10 5p4

Let’s play Electron Configuration Battleship Rules: 1-Each player uses a marker to draw one ship per sublevel.

Let’s play Electron Configuration Battleship Rules: 1-Each player uses a marker to draw one ship per sublevel.

Let’s play Electron Configuration Battleship 2-Each ship should be arranged vertically or horizontally and should occupy the specified boxes.

Let’s play Electron Configuration Battleship 3) You have 4 ships S-sublevel (Destroyer) 2 spaces P-sublevel (Cruiser) 3 spaces D-sublevel (Battleship – 4 spaces F-sublevel (Aircraft) – 5 spaces

Let’s play Electron Configuration Battleship 4) Player #1 draws a chip and “fires” at an element by giving he appropriate electron configuration. Red – standard notation Blue – noble gas notation

Let’s play Electron Configuration Battleship 5) Player #2 confirms the targeted element by saying its element name and declares it a “hit” or “miss”.

Let’s play Electron Configuration Battleship 6) Both players record the “hit” with and X OR “miss” with an O Top board – your guesses Bottom board – your opponents guesses

Let’s play Electron Configuration Battleship 7) First player to sink all your opponent’s ships WIN!!!!
