is the below the correct electronic configuration for arsenic?

Arsenic:[Ar]4s23d104p3

yes

To determine if the given electronic configuration is correct for arsenic, we need to verify it.

The atomic number of arsenic is 33, which indicates that it has 33 electrons. Let's break down the electronic configuration step by step:

- The noble gas preceding arsenic in the periodic table is argon (Ar), which has an electronic configuration of 1s^22s^22p^63s^23p^6.
- Next, we fill in the remaining electrons for arsenic.

The electron configuration of arsenic can be determined by following the Aufbau principle and Pauli exclusion principle, which state that electrons fill the available electronic orbitals in order of increasing energy.

From the noble gas configuration of argon, we would start filling the 4s orbital, which can hold up to 2 electrons. The slater's rules can be used to determine the effective nuclear charge that each electron experiences.

Next, we would move to the 3d orbital, which can hold up to 10 electrons, and then fill the 4p orbital, which can hold up to 6 electrons.

Putting it all together, the correct electron configuration for arsenic would be:
1s^22s^22p^63s^23p^64s^23d^104p^3

Therefore, the given electronic configuration for arsenic: [Ar]4s^23d^104p^3 is incorrect.
