X refers to Beryllium
Y refers to Sodium
Z refers to Magnesium
the element which has the highest inonisation is Beryllium since it's atomic number is 4 and it is a metal

Answered by Gurbrahm

Ionisation Energy is the energy required to remove the loosely bound electrons from outermost shell. As for metals it is easy to do so for them and non metals have higher effective nuclear charge which hold the electrons tight, so for element X with atomic number 4, it would be difficult for it to lose easily louder bound electrons so it will have highest infusion energy.

Hope you got your answer.

abhi111241: no

abhi111241: not infusion

abhi111241: its ionisation

Gurbrahm: see ..evrey atom has a tendency to get 8 electrobs in its last shell

mamitadlee8: thanks

Gurbrahm: and yes.... some energy is required to lose electrons to get 8 electrons in its last shell. according to the terms of periodic table, ionisation Energy increases from leg to right in a period and decreases down the group

Gurbrahm: so that's why beryllium had highest ionisation Energy among the given elements
