(Print) Use this randomly generated list as your call list when playing the game. There is no need to say the BINGO column name. Place some kind of mark (like an X, a checkmark, a dot, tally mark, etc) on each cell as you announce it, to keep track. You can also cut out each item, place them in a bag and pull words from the bag.

Strong electrostatic attraction between two nuclei and the shared pair of electrons between them
covalent bond
exactly the same number and arrangement of electrons
isoelectronic
pair of electrons in the outer shell of one of the atoms in a molecule or ion which is not involved in bonding
lone pair
Crystal structure in which all atoms or ions are linked by a network of strong bonding
Giant structure
energy required to break one mole of the bonds in a substance in the gaseous state
bond energy
angle between two covalent bonds in a molecule or giant covalent structure
bond angle
distance between the nuclei of two bonded atoms in a molecule
bond length
covalent bonds linking the atoms in a molecule
Intramolecular forces
atoms of the same element which have the same number of protons but a different number of neutrons
isotopes
bonding electrons which are not fixed in a bond between two atoms
delocalised electrons
shared electrons are drawn towards the atom with the stronger pull on the electron
polar covalent bond
Groups of atoms held together by strong covalent bonding within the molecule but weak forces of attraction between the molecules
Simple molecular structure
number of protons plus neutrons of an atom in its nucleus
mass number
ability of an atom to attract the bonding electrons in a covalent bond
electronegativity
solution that contains as much of the solute as possible at a given temperature
saturated solution
the energy needed to remove one mole of electrons from one mole of gaseous atoms or ions of an element
ionisation energy
measure of concentration of saturated solution of a solute at specified temperature
solubility
energies of electrons in atoms
energy levels
effect of inner electrons which reduces the pull of the nucleus on the electrons in the outer shell of an atom
shielding
intermolecular forces that exist between all molecules
London forces
chemical which dissolves in a solvent to make a solution
solute
indication of the extent to which the electron cloud in a molecule or ion can be distorted by nearby electric charge
polarisability
strong electrostatic attraction between oppositely charged ions
ionic bonding
molecules that contain polar bonds which do not cancel each other
polar molecules
average mass of an atom of an element relative to 1/12th of the mass of an atom of carbon-12
relative atomic mass
strong electrostatic attraction between metal ions and 'sea' of delocalised electrons
metallic bonding
weak attractive forces between molecules
Intermolecular forces
region of space around nucleus of an atom in which there is a 95% chance of finding an electron
orbital
regular three-dimensional arrangement of atoms or ions in a crystal
lattice
half the distance between two nuclei of two covalently bonded atoms of the same type
ionic radius
