Interpretation:
It is to be identified whether Statement I is correct or not. If the statement I is correct explain the reason given is explaining statement I or not.
Concept Introduction :
The first ionization energy is the energy required to extract the outermost electron from an isolated neutral atom. Ionization energy depends on the size of the atom and the electronic configuration of the element.
Answer to Problem 12STP
Statements I and II both areincorrect.
Explanation of Solution
Noble gases have the smallest ionization energy because they have complete octets and hence, they are stable and chemically unreactive. So, they neither gain nor lose electrons. As they are stable, a huge amount of energy is required to remove an electron. So, Nobel gases have the highest ionization energy.
Thus, the statement I is incorrect.
Atomic size decreases across the period or from left to right. So, the atomic size will increase from right to left.
So, statement II is also false.
