For drawing Lewis structures, how do you know which atom in the molecule has the lowest ionization energy?

You can know the lowest ionization energy of elements by where they are on the periodic table. Left to right across a period, and upward within group indicate increasing ionization energy.

However, hydrogen is an exception. It has a high ionization energy.

Ionization energy has periodicity.

Hi! You can know this by using your periodic table, but be careful because hydrogen is a bit tricky.

For connection purposes: think of ionization energy as having a similar trend to electronegativity. The elements that pull electrons more towards themselves when bonding are the same atoms that it is difficult to remove an electron from.

Ionization energy has a trend, but there are many outliers based on electron structures.

Are there other exceptions to ionization energy (e.g., hydrogen)?
