  1. Periodic Trends Ionization energy, atomic radius, ionic radius, electronegativity By Oscar Trejo Period 2

  2. Ionization Energy (Periods) • As you go across the periodic table the ionization energy increases. • Boron has 800.6 and across from it nitrogen has an ionization energy of 1402.

  3. Ionization Energy (Groups) • As you go down the periodic table the ionization energy decreases. Boron 800.6 to Thallium's 589.4.

  4. Atomic Radius (Periods) • Atomic radius across the periodic table decreases. Gallium is 130 and across the period to Arsenic which has an atomic radius of 125.

  5. Atomic Radius (Groups) • Atomic radius in the groups of the periodic table increase as they go down. Arsenic 125 increases to 143 in Bismuth.

  6. Ionic Radius (Period) • As you go across the periodic table the ionic radius in a period increases. • The element nitrogen has an ionic radius of 25 to fluorine’s 133.

  7. Ionic Radius (Groups) • The ionic radius in the periodic table tends to increase as you go down the families. • Arsenic has an ionic radius of 78, which increases to Bismuth’s 103.

  8. Electronegativity (Periods) • Electronegativiy in the periodic table increase along the periods. • Gallium’s electronegativity is 1.81 it increases along the period to arsenic’s 2.2

  9. Electronegativity (Groups) • In the electronegativity of the periodic table, the groups decrease as you go down them. • Boron 2.04, gallium 1.81, thallium 1.62 as you can see elements electronegativity does decrease.

  10. Density (Periods) • Density across the periodic table for the most part does decrease. • Boron has a density of 2.34, Nitrogen has a density of 1.25, while fluorine is 1.70.

  11. Density (Groups) • Going down the element families the density increases as you go down them. Nitrogen 1.25, Arsenic 5.73, Bismuth 9.75.

  12. The Periodic Trends • Ionization energy in periods increases, but in groups decrease. • Atomic radius in periods decrease while in groups the radius in elements increases. The same can be said for density. • Ionic radius in periods increases and the ionic radius decreases in groups. • Electronegativity increase in periods and decrease in groups.
