There is huge difference in ionisation energy between IE4 and IE5.
This means, lots of energy are required to remove 5th electron.
So, after 4 electrons are removed, the element has acquired noble gas configuration,.
So, ether are 4 valence electrons in the element.
The element in period 2 with 4 valence electrons is Carbon
Answer: C
