12 Aqua Complexes of First Row

Guided Practice This will comprise of 5 steps Step 1 Total # of electrons Step 2 e config sequence superscripts Step 3 Fill in superscripts Step 4 Remove unoccupied subshells Step 5 Apply the pirate rule

I Do Guided Practice I will show you how to write the electron configuration of Chromium Cr Step 1a determine the total number of electrons in the atom Number of electrons = atomic number For Chromium this is 24

I Do Guided Practice Step 2 You need to know and use the following sequence 1s, 2s, 2p, 3s, 3p, 4s, 3d, For transition metals we only need to go up to 3d Step 3 Enter the electrons into the sequence. Aufbau principle states that you must start with the lowest energy level

I Do Guided Practice I have 24 electrons so 1s 2, 2s 2, 2p 6, 3s, 3p, 4s, 3d 14 left 1s 2, 2s 2, 2p 6, 3s 2, 3p 6, 4s, 3d 6 left 1s 2, 2s 2, 2p 6, 3s 2, 3p 6, 4s 2, 3d 4 **If the transition metal begins with a C then move one electron from the 4s to the 3d orbital 1s 2, 2s 2, 2p 6, 3s 2, 3p 6, 4s 1, 3d 5

Example 2 Electron configuration for Ti Step 1 How many electrons Ti has an atomic number of 22 Step 2 write out sequence 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, Step 3 enter electrons 1s 2, 2s 2, 2p 6, 3s 2, 3p 6, 4s 2, 3d 2

Step 4 check using the periodic table Count from the beginning of the d block Since Ti is the second transition metal then the most outer orbital will be 3d 2

WWW We Do Write the electron configuration for Copper.

Independent Practice 1) Vanadium has an electron configuration of 1S 2 2S 2 2P 6 3S 2 3P 6 4S 2 3d 3 place arrows in each of the boxes to represent the electrons. 2) Given the atomic number and symbol, which metal is most likely to be a catalyst in an industrial process? A. 20 Ca calcium B. 13 Al aluminum C. 24 Cr chromium D. 50 Sn tin

3. Which letter represents a Transition Metal? A. element E B. element G C. element Y D. element R 4. Which statement is generally TRUE when comparing the Group 1 Alkali Metals with the central block of Transition Metals? A. only Transition Metals are good conductors of electricity B. both are typically hard metals C. both have high melting points D. Alkali Metals are more reactive than Transition Metals

5. Which is a Noble Gas? A. element 29 B. element 37 C. element 26 D. element Which statement is generally TRUE when comparing the Group 1 Alkali Metals with the central block of Transition Metals? A. only Transition Metals are good conductors of electricity B. both consist of reactive metals C. both have high melting points D. Alkali Metals are soft, Transition metals are hard As you travel across the transition metals from Sc through to Zn what happen to atomic radius
