CHEM Polar and Nonpolar covalent bonds
what is a molecule?
2 or more atoms bonded together
what are the diatomic molecules? (do not include subscript)
HOFBrINCl
give the diatomic molecules with subscripts
H₂O₂F₂Br₂I₂N₂Cl₂
equal sharing of valence electrons create... bonds
non polar covalent
explain the cause behind a polar covalent bond
one nucleus attracts the shared valence electron pairs more strongly to create a molecule with a dipole
unequal sharing of valence electrons create... bonds
polar covalent
explain the cause for a non polar covalent bond
the electrons spend an equal time around both nuclei so there is no separation of charge
define what a non polar covalent bond is
a chemical bond created by the equal sharing of valence electron pairs between atoms
define what a polar covalent bond is
a chemical bond created by the unequal sharing of valence electron pairs between atoms
define what a diatomic molecule is
a molecule made up of 2 atoms of the same element
define dipole
a separation of charge across a polar molecule creating a slightly positive and a slightly negative end
