Element Y reacts with oxygen to form the compound Y2O and has the lowest ionization energy of any Period 4 element on the periodic table. Identify this element.
Homework Answers
Ionisation energy increases from left to right in a
period.
Since this element has lowest ionisation energy, it should be in
group 1.
The element in group 1 and period 4 is Potassium
So, the element is Potassium
Its symbol is K
