Expert Solution

solution of part A

• The given excited state orbital fill diagram of an atom is ,

• Since, we know that the atomic number of argon is 18 and it has 18 electrons in it. In addition, there is also 2 electrons in 4s, 10 electrons in 3d and 4 electrons in 4p.

• Therefore, the total number of electrons in the given atom is 34 ( ∵ 18 + 2 + 10 + 4 )

• Since, we know that the total number of electrons in an atom is equal to the atomic number of an atom. Thus the atomic number of given atom is 34.

• Therefore, the given atom is Selenium which is represented by the chemical symbol Se
