Electronegativity and Ionization EnergyA series of free High School Chemistry Video Lessons from Brightstorm.
Electronegativity Electronegativity is a quantitative measure of how tightly an atom holds onto its electrons. Bond polarity results from imbalanced electronegativities of the atoms involved in bonding. Electronegativity is a periodic trend which increases as you go up and to the right along the periodic table.
Ionization Energy - Periodic Trends Ionization energy is the minimum energy required to remove an electron from the ground state of an atom. Ionization energy is a periodic trend which increases going from top to bottom and left to right across the periodic table.
Atomic Radii - Ionic Radii Atomic and ionic radii are distances away from the nucleus or central atom that have different periodic trends. Atomic is the distance away from the nucleus. Atomic radius increases going from top to bottom and decreases going across the periodic table. Ionic radius is the distance away from the central atom. Ionic radius increases going from top to bottom and decreases across the periodic table.
