Understanding Periodic Trends in Atomic Ionizability

What is ionization in the context of atomic chemistry?

• The process of an atom splitting into two smaller atoms

• The conversion of an atom into a cation by losing an electron

• The conversion of a cation into a neutral atom

• The process of an atom gaining an electron

Which element among barium, xenon, and neon has the highest ionization energy?

• Barium

• Xenon

• Neon

• All have the same ionization energy

In the periodic table, which direction indicates an increase in ionization energy?

• From top to bottom

• From right to left

• From bottom left to top right

• From bottom right to top left

Which element among argon, francium, and germanium has the lowest ionization energy?

• All have the same ionization energy

• Germanium

• Francium

• Argon

What is the trend of ionization energy as you move across a period from left to right?

• It increases

• It decreases

• It remains constant

• It first decreases then increases
