Question

1 what is the noble gas configuration for zinc? * (0.5 points) a ar4s²4d¹⁰ b kr4s²3d¹⁰ c ar4s²3d¹⁰ d ar3s²3d¹⁰

Explanation:

Zinc has an atomic number of 30. The noble - gas core before zinc is argon (Ar) which has 18 electrons. The remaining 12 electrons fill the 4s and 3d orbitals as 4s²3d¹⁰ according to the Aufbau principle, Pauli - exclusion principle, and Hund's rule.

Answer:

C. [Ar]4s²3d¹⁰
