Electronegativity and Periodic Trends
- Electronegativity
- Ability of an atom to atract an electron
- Fluorine
- Highest electronegativity
- Highest electronegativity
- Halogens
- Sodium, a
metelectronegativeal, is not
- Nonmetals
- Increases as you go up the periodic table
- Noble gases don´t have
electronegativity
- The one with higher positive charge, is more electronegative
- +need for electrons to be neutral:
+electronegativity
- Francium
- Less electronegativity
- Less electronegativity
- Tells how much it
wants an electron
- Ability of an atom to atract an electron
- Electropositive
- Gives electrons
- Metals
- Gives electrons
