10 points! please! In period 1, what group or family of elements has the largest atomic radius?
In period 1, what group or family of elements has the largest atomic radius?
i don't see how there can be a group or family in 2 elements.
i just started this so maybe you can help.
one other question:
in period 3, what group or family has the lowest first ionization energy?

Atomic Radius Increases as you go down & Decreases as you go across
Ionization Energy Increases as you go across & Decreases as you go down
Question #1 Hydrogen (H)
Question #2 Sodium (Na)

Period 1, would be alkali metals with largest radius.
Period 3, lowest ionization energy would be Alkali metals too.
Hint for future: Going down a periodic table the radius increases.
Going across a periodic table ->, the radius increases
The ionization energy, generally speaking, increases from left to right and decreases going top to bottom.
