Unit 6- Bonding Flashcards
Ionic bond
Electrons are transferred from one atom to another
Chemical bond
The attraction that holds atoms together
Covalent bond
Electrons are shared between atoms
Electronegativity
The attraction for shared electrons
Electrostatic force
The attraction (or repulsion) between charged particles
Pure covalent bond
Electrons are shared evenly
Polar covalent bond
Electrons are shared unevenly
Crystal
A regular geometric pattern
Molecule
The smallest particle if a compound
Ion
A charged particle
Cation
A positive ion
Anion
A negative ion
Electrolyte
Conducts electricity when dissolved
Single bond
Two electrons (1 pair) are shared
Double bond
4 electrons (2 pairs) are shared
Triple bond
6 electrons (3 pairs) are shared
Resonance
Bonding arrangements switch between 2 or 3 degenerate structures
Isomer
Molecules with the same formula but with different structures
Ionization energy
The energy required to remove one valence electron
Electron affinity
The energy given off when the atom gains one electron
