Answer

Brief Explanations:

Zinc has an atomic number of 30. The electron - filling order follows the Aufbau principle. The first shell (n = 1) has 1s sub - shell which can hold 2 electrons (1s²). The second shell (n = 2) has 2s and 2p sub - shells, with 2s holding 2 electrons and 2p holding 6 electrons (2s²2p⁶). The third shell (n = 3) has 3s, 3p, and 3d sub - shells, with 3s holding 2 electrons, 3p holding 6 electrons, and 3d holding 10 electrons (3s²3p⁶3d¹⁰). The fourth shell (n = 4) has 4s sub - shell which holds 2 electrons (4s²). So the electron configuration of zinc is 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰.

Answer:

1s²2s²2p⁶3s²3p⁶4s²3d¹⁰ (the last option)
