Chemical Bond — definition?
Force that holds atoms together in molecules.
Bond Formation — reason?
Atoms bond to achieve stable electron configurations.
Types of Bonds — examples?
Ionic, covalent, metallic, hydrogen bonds.
Ionic Bond — formation?
Transfer of electrons between metal and non-metal.
Covalent Bond — sharing?
Atoms share electron pairs to stabilize.
Metallic Bond — electrons?
Delocalized electrons shared among metal atoms.
Hydrogen Bond — attraction?
Weak attraction between H and F, O, N.
Lewis Theory — basis?
Electron dot structures for bonding visualization.
Octet Rule — goal?
Atoms seek 8 electrons in outer shell.
Bond Length — definition?
Distance between nuclei of bonded atoms.
VSEPR — purpose?
Predict molecular shapes based on electron pairs.
Resonance Structures — role?
Depict delocalized electrons in molecules.
Ionic Bond — ions involved?
Cations and anions attracted electrostatically.
Covalent Bond — polarity?
Depends on electronegativity difference.
Metallic Bond — properties?
Conductivity, malleability, ductility.
Hydrogen Bond — significance?
Influences water properties and biological structures.
Lewis Structures — depict?
Valence electrons and bonding patterns.
Octet Rule — exceptions?
Molecules like NO, BCl₃ violate it.
Bond Energy — indicates?
Strength of a bond; higher means stronger.
Molecular Shape — determined by?
Electron pair repulsion (VSEPR).
Resonance — effect?
Stabilizes molecules via electron delocalization.
Bond Type — transfer or sharing?
Ionic: transfer; Covalent: sharing.
Bond Characteristics — include?
Length, energy, order.
Molecular Shapes — VSEPR?
Linear, trigonal planar, tetrahedral, etc.
