10 cards from this deck
Atoms share pairs of electrons to form strong bonds
Electrons shared (covalent) vs transferred (ionic)
Atomic orbitals overlap, sharing unpaired electrons
Localised - only between shared pair and 2 nuclei
C forms 4, N forms 3, O forms 2, H forms 1 bond
Electron pairs not shared with another atom (non-bonding)
Period 3 onwards (d-orbitals available)
Two pairs of electrons shared between two atoms
Both electrons in shared pair come from same atom
Higher bond enthalpy = stronger bond
