Final answer:
Electronegativity, effective nuclear charge, and ionization energy increase from left to right across a row and from bottom to top of a column on the periodic table.
Step-by-step explanation:
On the periodic table, electronegativity, effective nuclear charge, and ionization energy generally increase from left to right across a row and from bottom to top of a column.
This is due to the increase in the number of protons in the nucleus as you move across a row, which results in a stronger attraction of the nucleus to electrons.
As a result, it becomes more difficult to remove electrons and the ionization energy increases.
The increase in effective nuclear charge also leads to an increase in electronegativity, which is the tendency of atoms to attract electrons.
