Question

match the trend to the correct description of its pattern. electronegativity ionization energy ionic size atomic radius decreases as you move across a period and increases as you move down the group. increases across a period and decreases down the group. most noble gases do not have a value for this. negative ions are larger than their neutral atoms. positive ions are smaller than their neutral atoms. increases across a period and decreases down the group.

Explanation:

Electronegativity increases across a period and decreases down a group, with most noble gases having no value for it. Ionization energy increases across a period and decreases down a group. Ionic size - negative ions are larger than neutral atoms and positive ions are smaller than neutral atoms. Atomic radius decreases across a period and increases down a group.

Answer:

Electronegativity: Increases across a period and decreases down the group. Most noble gases do not have a value for this.
Ionization Energy: Increases across a period and decreases down the group.
Ionic Size: Negative ions are larger than their neutral atoms. Positive ions are smaller than their neutral atoms.
Atomic Radius: Decreases as you move across a period and increases as you move down the group.
