Electronegativity:
– As you move to the right across a period of elements, electronegativity increases.
– As you move down a group, electronegativity decreases.
Atomic radius:
– As you move down a group, atomic radius increases.
– As you move across a period, atomic radius decreases.
First Ionization Energy:
– As you move down a group, first ionization energy decreases.
– As you move across a period, first ionization energy increases.
