Question

Atomic number of elements X, Y and Z are 4, 11, 12. Which element has highest ionisation energy? Why?

Answer 1

✨✨✨Heya mate !! ✨✨✨

your answer .... ✍️✍️

◼️The element with smallest size will have highest ionization energy . Here it will be the element having lowest atomic number .

◼️Since , here atom X has Lowest atomic number , i.e., 4 .

✳️So , your answer is X.


Hope helps ❤️❤️

Answer 2

"Atomic number of element X" has highest ionisation energy.

Explanation:

• Ionisation energy is the "minimum energy required to remove a loosely bound electron" from the outer electron orbit because the grouping of electrons in various shells is according to 2,8,18,32 sequence.
• According to this, the significant amount of energy required to drag out an electron from the "closest shell to the nucleus is higher".
• An alternative method of reaching this conclusion is that X is the most stable out of the given options.
• Also, the element which is small size will have the highest ionisation energy.
