I can explain how electronegativity and ionization energy change across periods and groups in the periodic table.
- 1
Coulomb's law states that the magnitude of the force between two charged particles is proportional to the charge on each particle and inversely proportional to the square of the distance between them.
- 2
Effective nuclear charge (Zeff) is the net positive charge experienced by valence electrons in an atom and can be approximated by subtracting the number of core electrons from the atomic number.
- 3
Ionization energy generally increases across a period (from left to right) and decreases down a group, while atomic radius generally decreases across a period and increases down a group.
