How does the atomic radius change from top to bottom in a
group in the periodic table? Why?
A 100
It tends to increase. From top to bottom, electrons are farther
away.
A 100
What is electronegativity?

Why?
A 300
Increases. Stronger attraction from the nucleus of the electrons
in the same energy level.
