write the condensed (noble - gas) electron configuration of arsenic. for multi - digit superscripts or coefficients, use each number in succession.
Answer
Explanation:
Step1: Find the atomic number of arsenic
Arsenic (As) has an atomic number of 33.
Step2: Identify the nearest noble - gas
The nearest noble - gas with an atomic number less than 33 is argon (Ar), which has an atomic number of 18.
Step3: Write the electron configuration after the noble - gas
We need to account for the remaining 33 - 18 = 15 electrons. The electron configuration after [Ar] is $4s^{2}3d^{10}4p^{3}$.
Answer:
$[Ar]4s^{2}3d^{10}4p^{3}$
