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
