4.1 - Types of Chemical Bonds Flashcards
ionic bond
chemical bond between oppositely
charged ions.
ionic compound
forms between a positively
charged metal (lost an electron), and a negatively
charged non-metal. (gained an electron) EG.
Sodium Chloride NaCL.
Electrostatic attraction between positively
charged sodium ions and negatively charged
chloride ions creates a …
crystal lattice structure
covalent bond
a chemical bond that
results when atoms share the bonding
electrons between non-metal atoms.
bonding electron pair
an electron pair
involved in bonding, found in the space
between 2 atoms.
lewis theory of bonding
Atoms and ions are stable if they have a full
valence shell of electrons.
Electrons are most stable when they are paired.
Atoms form chemical bonds to achieve a full
valence shell of electrons.
A full valence shell can be achieved in ionic
bonding by an exchange of electrons between
metal and non-metal atoms.
A full valence shell of electrons may be achieved
by the sharing of electrons in molecular
compounds between non-metal atoms.
octet rule
Atoms form the most stable substance when
they are surrounded by 8 electrons in their
valence shells.
