What trends do you see on the periodic table for ionization energy and what causes these trends?
Ionization energy increases across a Period (from left to right); and decreases down a Group (top to bottom).
The Noble gases have the highest ionization energies because they have the greatest nuclear charge; on the basis of simple electrostatics, this makes sense because electrons are added to the same shell and the nuclear charge increases sequentially as one moves to the right of the Periodic Table. Nucleus-electron attraction should be minimized as one moves down a group because the valence shell of electrons moves farther away from the electropositive nucleus.
You are a physical scientist, so don't just take my word for it. Instead, obtain a list of ionization energies and attempt to explain this using the Periodic Table. Good luck.

The further to the right and the higher you go, the higher the ionization energy.
The energy needed to extract a single electron from an outer shell is known as ionization energy, and it is primarily determined by two factors:
The reason why ionization energy trends go up and left, even though a downward trend would result in an increase in nuclei's mass, is that a change of one in the number of shells is more pronounced than a change of one in the number of nuclear mass.
I hope it's helpful ;D.

The trends for ionization energy on the periodic table generally increase across a period from left to right and decrease down a group from top to bottom. This is primarily caused by changes in effective nuclear charge and atomic size.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
