write the electron orbital notation for the following element. 19. manganese: write the standard electron configuration for the following elements. no short - hand versions. 20. aluminum: 21. arsenic: write the noble gas short - hand electron configuration for the following elements. 22. zirconium:

Answer

Explanation:

Step1: Recall electron - filling rules

Electrons fill orbitals in order of increasing energy (1s < 2s < 2p < 3s < 3p < 4s < 3d < 4p etc.). The s - orbital can hold 2 electrons, p - orbital can hold 6 electrons, d - orbital can hold 10 electrons and f - orbital can hold 14 electrons.

Step2: Determine electron configuration of Aluminum (Al)

Aluminum has an atomic number of 13. 1s²2s²2p⁶3s²3p¹

Step3: Determine electron configuration of Arsenic (As)

Arsenic has an atomic number of 33. 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p³

Step4: Determine electron configuration of Manganese (Mn)

Manganese has an atomic number of 25. 1s²2s²2p⁶3s²3p⁶4s²3d⁵

Step5: Determine noble - gas short - hand of Zirconium (Zr)

Zirconium has an atomic number of 40. The noble gas before Zr is Kr (atomic number 36). [Kr]5s²4d²

Answer:

  1. Manganese: 1s²2s²2p⁶3s²3p⁶4s²3d⁵
  2. Aluminum: 1s²2s²2p⁶3s²3p¹
  3. Arsenic: 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p³
  4. Zirconium: [Kr]5s²4d²
