Electron Configuration and The Periodic Table

• What is the focus of this video series?

  Electron configuration and periodic table links
• How do scientists categorize the periodic table?

  Into different blocks based on subshells
• What is the highest energy electron subshell in the S block?

  S subshell
• What is the highest energy electron subshell in the P block?

  P subshell
• What is the highest energy electron subshell in the D block?

  D subshell
• What is the highest energy electron subshell in the F block?

  F subshell
• Why is the F block removed in this video?

  It won't be used in this video
• How can you check if an electron configuration is correct?

  By using the periodic table
• How many electrons does silicon have?

  14 electrons
• What is the electron configuration of silicon?

  1s2 2s2 2p6 3s2 3p2
• How does the position of silicon in the periodic table confirm its electron configuration?

  It shows the correct filling of subshells
• What does the first row of the D block represent?

  Electrons in the D subshell of the third shell
• What is the electron configuration of nickel?

  1s2 2s2 2p6 3s2 3p6 3d8 4s2
• How do the subshells fill with electrons in nickel's configuration?

  In order from lowest to highest energy
• What is the significance of the 4s subshell in relation to the 3d subshell?

  The 4s subshell fills before the 3d subshell
• What is the process to write the shorthand electron configuration of elements?

  1. Identify the element's atomic number
  2. Determine the electron configuration
  3. Use noble gas notation for shorthand
  4. Fill subshells according to energy levels
