Electronegativity Quiz Flashcards
When does ionization energy decrease?
Moving down a group.
Ionization Energy
Energy required to remove an electron from an atom in its gas state
When does ionization energy increase?
Moving left to right across the PTE
Atom size
Increase as you move down, decreases moving left to right.
Bond
Force of attraction holding atoms together
Electronegativity
The relative ability of an atom in a molecule to attract shared or bonding electrons
Ionic bonds
One or more electrons are pulled away from a metal by a nonmetal
Resulting ions attract and clump together in an ordered pattern called a crystalline structure
Covalent Bonds
Electrons are simultaneously attracted to two nuclei
Common making two of the same elements
Polar covalent bond
If atoms are different elements but electrons are simultaneously attracted to two nuclei
Dipole moment
One side of molecule is slightly negative while other side is slightly positive
Continuum of polarity
Between totally ionic bonds and totally covalent bonds
Important for almost all stable compounds
The atoms in the compound achieve noble gas electron configurations in the compound
