Question 4 Unsaved When writing electron configuration the 3d block comes after the 4s block. Question 4 options: True False
zmey [24]

Answer:

True

Explanation:

Sublevels do not fill up in numerical order but there is a certain manner in which they are filled. The pattern is shown below:

  1s 2s 2p 3s 3p 4s 3d 4p 5s 4d 5p e.t.c

 We see that the 4s gets filled before the 3d sublevel.
