In this lesson, we will learn how to use the periodic table to deduce the electron configurations of main group (s- and p-block) elements.
Q1:
What is the electronic configuration of the Na+ ion?
Q2:
What is the name and chemical symbol for the most stable ion of magnesium?
Q3:
In which group of the periodic table do atoms have a valence shell electron configuration of (𝑛−1)𝑛ds1?
