Question

Write the correct electron configuration for Se. Express your answer in complete form in order of increasing orbital energy as a string without blank space between orbitals. For example, 1s22s2 would be entered as 1s^22s^2.

Answer 1

`1s^22s^22p^63s^23p^64s^23d^(10)4p^4`

Step-by-step explanation:

The atomic number of Se is 34

Its electronic configuration is the distribution of electrons of an atom in the atomic orbitals

The electronic configuration of Selenium (Se) is

`1s^22s^22p^63s^23p^64s^23d^(10)4p^4`

Note that 4s has less energy than 3d so it is written before
