Which element has the lowest ionization energy?

A. Argon (Ar)
B. Bromine (Br)
C. Cesium (Cs)
D. Nickel (Ni)

Asked by armentaangel

Answer (3)

C the answer is cesium, study's show that it has the lowest ionization out of all elements. Hope this helped!

C. Cesium because ionization energy increases as you move from left to right across a period and from down up a column of the periodic table, making a diagonal pattern from the bottom left corner to the top right of the periodic table.

Cesium (Cs) has the lowest ionization energy among argon (Ar), bromine (Br), and nickel (Ni). This is due to its position in the periodic table where ionization energy decreases down a group and increases across a period. Therefore, the correct option is C. Cesium (Cs).
