What direction on the periodic table does the atomic radius of an atom get larger?

down + left

What direction on the periodic table does the ionization energy of an atom get larger?

up + right

What direction on the periodic table does the electronegativity of an atom get larger?

up + right

What direction on the periodic table does the metal reactivity of an atom get larger?

down + left (away from stair step)

What direction on the periodic table does the nonmetal reactivity of an atom get larger?

up + right (away from the stair step)

What does atomic radius mean?

the distance from the center of the atom (nucleus) to the furthest electron orbital

What does ionization energy mean?

the energy needed to remove an electron from the outermost energy level (the smaller an atom is, the more energy it will take, because the outermost energy level is closer to the nucleus)

What does electronegativity mean?

indicates how strongly an atom of that element attracts electrons to itself (similar to ionization energy: the smaller the atom, the stronger its electronegativity is because the outermost energy level is closer to the pull of the nucleus)

What is the pattern for metal reactivity? 

as a metal gets larger, it gets more reactiv

What group of elements are excluded from the periodic trends?

noble gases (far right column)

What is the pattern for nonmetal reactivity? 

as atoms become smaller they become more reactive

Which has the greater atomic radius, Silver or Zirconium?

Zirconium

Which has the smaller atomic radius, Rubidium or Potassium?

Potassium

Which has more ionization energy, Copernicium or Calcium?

Copernicium

Which has less ionization energy, Tin or Boron?

Tin

Which has the greater electronegativity, Cadmium or Germanium?

Germanium

Which has less electronegativity, Vanadium or Yttrium?

Yttrium

Which metal has more reactivity, Barium or Platinum?

Barium

Which metal has less reactivity, Lithium or Lead?

Lead

Which nonmetal has more reactivity, Hydrogen or Arsenic?

Arsenic

Which nonmetal is less reactive, Selenium or Astatine?

Astatine
