Atomic Radius
What is the definition of Atomic Radius?
The distance between the center of the nucleus and the outermost electron
What is the definition of Ionization Energy?
The amount of energy necessary to remove an electron from the outermost electron orbital
What is the definition of electronegativity?
The ability of an atom to pull on (attract) electrons from another atom.
What is the left most block on the periodic table?

Bashful
How does Coulomb's Law affect atomic radius going across a period on the periodic table?
The increased number of protons increases the positive pull on the electrons, pulling them closer and decreasing the atomic radius.
How does Coulomb's Law affect Ionization energy going down a periodic table?
Going down a periodic table increases the number of electron orbitals on the atom, creating more distance between the nucleus and the electrons. This reduces the pull on the electrons, and therefore less energy is required to remove the electron.
How does Coulomb's Law affect electronegativity going across the periodic table (L to R)?
Going across the periodic table, the increased number of protons increases the nuclear charge, pulling stronger on its electrons. This means that the nucleus is more able to pull electrons from other atoms as as the nuclear charge increases.
