Tags & Description
chemical bond
is defined as attractive force that exist between atoms or group of atoms
covalent bond
that attraction between two atoms sharing a pair of electron
octet rule
in order for an atom to attain stability it must acquire a total of eight electron
lewis electron dot structure LEDS
special symbol developed by gilbert lewis
valence electron
the dots around the symbol represent the
bonding electron or shared electron
dot between the symbol represent the
non bonding electron
the other dot represent
water h2o molecule
forms when oxygen atom and 2 hydrogen atom shared electrons
atom
cobine together to stability
lewis structure
compose of the symbols of the dots
ionic bond
is formed when a metallic elements transfer its valence electron to a nonmetallic element
ion
is formed whenever an uncharged atom gains or loses electron
ionic compound
a subtance that is formed through ionic bonding is
covalent bond
formed by the sharing electron between non metals
polar and non polar
two types of covalent
non polar covalent bond
is formed when electrons are equally shared between two non metals
polar covalent bond
s formed when electrons are unequally shared between two non metal
single dash
the presence of single bond is
double covalent bond
sharing of two pairs electron
triple bond
sharing of three pairs electron
metals
are good conductors of heat and electricity
