The correct answer is:
A. Zirconium – [Kr]5s²4d²
Zirconium (Zr) has an atomic number of 40, and its electron configuration can be abbreviated using the noble gas preceding it, which is krypton (Kr). Therefore, the noble gas configuration for zirconium is [Kr]5s²4d².
Strontium (Sr), on the other hand, has an atomic number of 38 and would have the configuration [Kr]5s², making option D incorrect for strontium.
