the 3d orbital fills up before 4s...and you can write them in order of energy or by the numbers
Br - 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p5The noble gas notation form isBr- [Ar] 4s2 3d10 4p5Br- ion has 36 electrons and has the same electronic configuration as the noble gas krypton.Its noble gas notation is [Ar] 3d10 4s2 4p6
The electron configuration provided corresponds to the element iodine (I).
This electron configuration corresponds to the element calcium (Ca), which has 20 electrons. It follows the order: 1s2 2s2 2p6 3s2 3p6 4s2 3d10. Ca belongs to the group 2 elements and has a full 4s and 3d subshell.
The electron configuration for Yttrium (Y) is [Kr] 5s2 4d1.
Selenium has 5 filled electron shells. The electron configuration for selenium is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p4.
The complete electron configuration for the copper atom is 1s2 2s2 2p6 3s2 3p6 4s1 3d10.
The electron configuration of copper is: [Ar]4s13d10. It isn't 4s23d9 because Cu is able to obtain a more stable electron configuration when it takes an electron from the 4s and adds it to 3d. A half filled 4s and a completely filled 3d is more stable.

The abbrieviated electron configuration of copper is [Ar] 4s23d9

Technetium. The 4s2 is supposed to be written before the 3d10 and the 5s2 is supposed to be written before the 4d5.
The electron configuration for Cu using spdf notation is 1s2 2s2 2p6 3s2 3p6 3d10 4s1 4p6.
Because having a half-filled s sublevel, such as 4s1, followed by a filled d sublevel, such as 3d10 is more stable than having a filled s sublevel, such as 4s2, followed by a d sublevel that is almost full, such as 3d9, which is very unstable.
It is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6.
Copper is element number 29. Thus, neutral copper has 29 protons and 29 electrons. The first 29 orbitals are filled as 1s2 2s2 2p6 3s2 3p6 4s1 3d10, thus copper has only one valence electron in its 4th shell.
