the covalent bond Flashcards
covalent bond
a chemical bond that results from electron sharing ; the shared electrons are in the outer most energy levels
molecule
formed when 2 or more atoms bond covalently
true or false the majority of covalent bonds form between nonmetallic elements
ture
where does the most stable arrangement of atoms exist ?
at the point of maximum net attraction where atoms bond covalently
diatomic molecules
exist because the 2 molecules are more stable than the individual
lone pairs
unbounded pairs
single covalent bond
when only one pair of electrons is shared
bonding pair
the shared electron pair
lewis structure
used to represent the arrangement of electrons in a molecule , using dots or lines
group 17 and single bonds
the haloens have 7 valence electrons and form single covalent bonds with other nonmetals or halogens
group 16 and single bonds
can share 2 elections and form 2 covalent bonds to reach an octet
group 15 and single bonds
can form 3 single covalent bonds in order to reach an octet
group 14 and single bonds
can form 4 single covalent bonds in order to reach an octet
sigma bond
single covalent bond ; can be formed when a S orbital overlap S orbitals or P orbitals or when P orbitals overlap end to end
pi bond
formed when parallel orbitals overlap and share electrons
