how does an atom achieve noble gas configuration in a single bond
two atoms share two electons
why do atoms share electrons in covalent bonds
to attain noble gas configuration

nitrogen
which noble gas has the same elctron configuration as the oxygen in a water molecule
neon
which elements can form diatomic molecules joined by a single bond
hydrogens and halogens only
what is the name of the valence electrons that do not participate in bonding in diatomic oxygen molecules
unshared pair
which diatomic molecule is joined by a double colavelent bond
