C1 CHEMICAL BONDING Flashcards
Chemical bonding
The mutual interaction between atoms resulting from the attraction and
repulsion between their nuclei and valence electrons.
bond energy
The energy needed to break chemical bonds to form neutral atoms.
bond length
The average distance between the nuclei of two bonded atoms.
ionic bonding
The electrostatic interaction between cations and anions that involves the
transfer of electrons and forms a three-dimensional lattice structure.
dative covalent bonding
A bond that involves the sharing of an electron pair between atoms where
both electrons are donated by one of the two atoms.
molecule
It is a neutral group of two or more atoms which are bonded together
sufficiently strongly to act as a unit in chemical reactions.
bonding (shared) pair
It is the pair of electrons that is shared between two atoms in a covalent bond.
lone pair
It is a pair of electrons in the valence shell of an atom that is not shared with
another atom.
electronegativity
It is a measure of the tendency of an atom to attract a shared pair of electrons
towards itself.
polar covalent bond
A bond that is formed as a result of the unequal sharing of electrons between
two atoms.
no-polar (pure) covalent bond
The bond that is formed as a result of an equal sharing of electrons
between two atoms.
