Question 4

The electronic configurations of beryllium and magnesium are:

  • beryllium: 2.2
  • magnesium: 2.8.2

When beryllium and magnesium react, they lose electrons to form positive ions with a 2+2+2+ charge.

Suggest an explanation, in terms of their electronic configurations, why magnesium is more reactive than beryllium.
