Can someone help me figure out what the noble gas configurations for zirconium and holmium are?

[AW2020]

I am currently working on noble gas configurations in chemistry and I am having a hard time understanding why I got two questions wrong on a practice.

The instructions for the practice are here:

Write out the noble gas configuration for the element. Enter your answer with all values without any spaces, hyper scripts or subscripts

Example: S- (These are meant to be in exponential format) [Ne]3s23p4 --> [Ne]3s23p4

My questions are:

1. Write the noble gas configuration for Zr:

2. Write the noble gas configuration for Ho:

My answers were:

1. [Kr]5s24p64d2

2. [Xe]6s25p64f11

I am still getting the answers wrong. Where did I go wrong in my configurations?

You wrote to much p- Electrons.

Look up the total configuration of Krypton and Xenon.

[Mad as a hatter]

predicted electron configurations for transition elements and the lanthanide and actanides are often wrong, zirconium is 1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3d10, 4p6, 5s2 or [Kr] 4s2, 3d10, 4p6, 5s2 and holmium is 1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3d10, 4p6, 4d10, 5s2, 5p6, 4f11, 6s2 or [Xe] 4f11 6s2

Dont post answers for 3  year old threads, probably the people not more alive.
