Ionic bonds form when a metal transfers electrons to a nonmetal, creating oppositely charged ions that attract each other electrostatically.
Covalent bonds form when atoms share electron pairs to achieve stable electron configurations. Common between nonmetal atoms.
CH4 has 4 bonding pairs around carbon with no lone pairs, giving a tetrahedral geometry with 109.5 degree bond angles (sp3 hybridization).
Electronegativity increases left to right across a period (more protons attracting shared electrons) and decreases down a group (electrons farther from nucleus).
Hydrogen bonds form when H is bonded to highly electronegative atoms (F, O, N). In water, H bonded to O creates strong hydrogen bonds between molecules.
sp2 hybridization involves mixing one s and two p orbitals, producing 3 hybrid orbitals arranged in a trigonal planar geometry with 120 degree angles.
Water has the highest boiling point due to extensive hydrogen bonding network. Each water molecule can form up to 4 hydrogen bonds.
In a coordinate (dative) covalent bond, one atom provides both shared electrons. Example: NH4+ where N donates a lone pair to H+.
Pi bonds form from the lateral (sideways) overlap of unhybridized p orbitals. They are weaker than sigma bonds and found in double/triple bonds.
In metallic bonding, valence electrons are delocalized and shared among all metal atoms, forming an "electron sea" that gives metals their conductivity and malleability.
