Exceptions to Electron Configurations

[Abigail Urbina 1K]

Upon doing some of the practice problems and looking at the solutions manual, I saw that Tungsten didn't follow the same exceptions rule as copper and chromium do when it comes to electron configuration. You would originally think that you would leave make the d shell half-filled and leave the s orbital singly occupied, but you don't. When taking this into account for writing electron configurations for other electrons, does Tungsten not follow the same rules as copper and chromium because they are in the same periods where the f block exists?

I'm also curious as to why tungsten is not an exception like chromium and copper. From my knowledge, the exceptions with special configurations are chromium and molybdenum (s1d5) and copper, silver and gold (s1d10).
