Of the following,which element has the highest first ionization energy?
A)indium
B)rubidium
C)tin
D)strontium

Question

Quizplus · Accepted Answer

Tin (C) has the highest first ionization energy among the options given. Ionization energy generally increases across a period from left to right in the periodic table because the atomic radius decreases, causing the valence electrons to be more tightly bound to the nucleus. Among the options, tin is located furthest to the right in the periodic table, making its first ionization energy the highest.
