bottom
6
Which group has zero electronegativity? Why?
Halogens-They are happy with their number of electrons
Alkali metals-They want more electrons
Noble Gases-They want more electrons
Noble Gases-They already have a full valence electron shell.
7

8
How are reactivity and ionization energy related?
The lower the ionization energy the higher the reactivity.
The lower the ionization energy the lower the reactivity.
They are not related.
The higher the ionization energy the higher the reactivity.

14
As you move from top to bottom (down a group) on the periodic table, the
ionization energy
decreases? WHY??
Its easier to remove electrons that are close to the nucleus.
You cannot remove electrons.
Its harder to remove electrons that are farther from the nucleus.
Its easier to remove electrons that are farther from the nucleus.
