1
New cards
stability
is gained when sublevels are completely or half-filled with electrons
2
New cards
full sublevels
offer more stability than half-filled sublevels
3
New cards
ionic bonds (metal and nonmetal)
EN > 1.7
complete donation occurs
4
New cards
why ionic bonds are not true bonds
the elements in an ionic compound are only held together due to electrostatic charge attraction (coulombic force) between the ions
no orbitals are overlapping or hybridizing
5
New cards
ionic lewis dot
arrows show donation
6
New cards
polar covalent bonds (nonmetal & nonmetal)
EN 0.35-1.7
shared unevenly between the two atoms, results in partial charges forming on each atom
7
New cards
non-polar covalent bonds (nonmetal & nonmetal)
EN 0-0.35
even pull on electrons, even sharing of electrons and no charges
