Question

In the sixth period,the orbitals being filled are

Answer 1

THERE ARE 32 ORBITALS ( INCLUDING LANTHANUM SERIES) THAT ARE FILLED IN THE 6TH PERIOD OF THE MODERN PERIODIC TABLE.

Answer 2

Answer:

6s, 6p, 5d and 4f

Explanation:

The orbitals are filled in the sequence: 

1s2s2p3s4p4s3d4p5s4d5p6s4f5d6p

The sixth period (n = 6) contains 32 elements, and subsequent electrons fill up the 6s, 4f, 5d, and 6p orbitals in the following order: filling up the 4f orbitals begins with cerium (Z = 58) and concludes with lutetium (Z = 71), resulting in the lanthanoid series.
