chemistry ~ bonds

• Covalent bonding is the process by which two atoms share electrons to form a molecule.
• The number of shared pairs of electrons determines the type of covalent bond formed, with single bonds having one pair of shared electrons, double bonds having two pairs, and triple bonds having three pairs.
• Covalent bonds form when two atoms share one or more pairs of electrons to fill their outer shells.
• Covalent bonds are extremely strong bonds that hold atoms together in molecules and crystals.
• Ionic compounds have high melting points due to the strength of ionic bonds between oppositely charged ions.
• ionic bonding 


  the electrostatic attraction between positive and negative ions
• Lattice
