300
What group are the noble gases?
What is group 8A or 18?
300
What group on the periodic table contains elements in all three phases of matter (solid, liquid, gas)?
What is the halogens?
300
Atomic radius _______ as you go across a period (left to right).
What is decreases?
300
Why does fluorine have the highest electronegativity on the periodic table? (In terms of Coulomb's law).
What is because the distance between the nucleus and valence electrons is small, which increases the ability for fluorine to attract electrons.

This metal was once thought to be rare and expensive and is now used in disposable items.
What is aluminum?
400
What group(s) are the transition metals?
What is groups 3-12?
400
What element is the least reactive on the periodic table?
What is Helium?
400
The ionic radius of a cation is _______ than the atom of the same element.
What is smaller?
400
Why does the ionization energy trend occur the way it does down a group? (in terms of coulomb's law).
What is because the force of attraction has decreased with distance from the nucleus so it's easier to pull electrons from the atoms at the bottom of the group.
