What is the ground state electron configuration of arsenic?
Understand the Problem
The question is asking for the ground state electron configuration of arsenic, which involves determining the arrangement of electrons in the atom when it is in its lowest energy state.
Answer
[Ar] 3d10 4s2 4p3
The ground state electron configuration of arsenic is [Ar] 3d10 4s2 4p3
Answer for screen readers
The ground state electron configuration of arsenic is [Ar] 3d10 4s2 4p3
More Information
Arsenic has an atomic number of 33, which means it has 33 electrons. The electron configuration can be written more compactly using the noble gas shorthand notation, starting from Argon (Ar).
Tips
A common mistake is to forget the order of filling and mistakenly place 3d10 after 4p.
