which is the electron configuration for zinc? 1s²2s²2p⁶3s²3p⁶4s²3d⁸ 1s²2s²2p⁶3s²3p⁶4s¹3d¹⁰…

Brief Explanations:

Zinc has an atomic number of 30. According to the Aufbau - principle, electrons fill orbitals in order of increasing energy. The electron configuration is $1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}$.

Answer:

$1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}$ (the last option)
