  • what is covalent bonding
    when non-metals bond by sharing electrons
  • what makes the covalent bond extra strong
    the positively charged nuclei of the bonded atoms are attracted to the shared pair of electrons by electrostatic forces
  • what does one single covalent bond mean
    one extra electron for each atom
  • what does it create enough bonds to do
    fill the outer shell
  • what does covalent bonding happen in
    non-metal compounds and elements
  • what do dot and cross diagrmans show
    where th electrons in the bond come from
  • what do dot and cross diagrams not show
    the relative size or how they are arramged
  • what does a ball and stick diagram show
    connections in large molecules
  • what do ball and stick diagrams not show
    the 3D structure, where the electrons come from and which atom etc
  • what do 3D models show
    atoms, bonds and arrangments
  • what do 3D models not show
    where the electrons came from. they can also become confusing with large molecules
  • what are hydrogen atoms bonded by
    one single covalent bond
  • what are chlorine atoms bonded by
    single covalent bond
  • what are oxygen atoms bonded by
    double covalent bond
  • what are nitrogen atoms bonded by
    triple covalent bond
  • what is hydrochloric acid bonded by
    one single covalent bond
  • what is methane bonded by
    4 single covalent bonds
  • what is water bonded by ( a polar moleucle)
    2 single covalent bonds
  • what do substamces containing convalent bonds have in terms of structure
    simple moiclecular structures
  • what are the atoms within the molecle sheld together by
    very strong molecular
  • what do the bonds between molecules have
    weak intermolecular bonds of attraction
  • why do the simple molecular compounds have low melting and boiling points
    only a small amount of energy is needed to break the weak intermolecular bonds
  • what are most molecular substances usually at room temp
    liquids or gases
  • why dont molecularcompounds conduct electricity
    particles arent charged or freely-moveable
  • why do boiling points increase as the molecules get bigger
    intermolecular forces increase so more energy is needed to break the bonds
