Answer 1

Answer #1

There is huge difference in ionisation energy between IE3 and IE4.

This means, lots of energy are required to remove 4th electron.

So, after 3 electrons are removed, the element has acquired noble gas configuration,.

So, there are 3 valence electrons in the element.

Al has 3 valence electrons
Answer: D) Al
