write the electron configuration of an atom of the element highlighted in this outline of the periodic table: hint: you do not need to know the name or symbol of the highlighted element!
Answer
Explanation:
Step1: Identify the period
The element is in the 4th period. So, we start with the noble - gas core of the previous period. The noble gas at the end of the 3rd period is Ar. So, we start with [Ar].
Step2: Fill the sub - shells in the 4th period
In the 4th period, we first fill the 4s sub - shell (2 electrons), then the 3d sub - shell (10 electrons), and then the 4p sub - shell. Since the element is in the 5th position in the p - block of the 4th period, there are 5 electrons in the 4p sub - shell. The electron configuration is [Ar]4s²3d¹⁰4p⁵.
Answer:
[Ar]4s²3d¹⁰4p⁵
