Question

[Ar]4s23d104p3 is the electron configuration of a(n) ________ atom.

Answer 1

Answer: The given configuration is of Arsenic atom.

Explanation:

Electronic configuration tells us about the number of electrons that are present in an atom. It also determines the atomic number of an element.

For the given configuration:  $[Ar]4s^23d^{10}4p^3$

Number of electrons present in argon = 18

So, total number of electrons in the given configuration = 18 + 2 + 10 + 3 = 33

The element having atomic number '33' is Arsenic.

Hence, the given configuration is of Arsenic atom.

Answer 2

[Ar]4s23d104p3 is the electron configuration of a(n) __As______ atom.
