of electrons per shell
2, 8, 8
electrons form what bonds
chemical bonds
valence electrons are
electrons that bond in the outermost shell
electronegativity
measure of atom’s ability to attract atoms to itself
chemical bond
attraction between two atoms, ions, or molecules
types of covalent bonds
polar or nonpolar
ionic bonds
bond between two oppositely charged ions
any element bonded to itself is what type of bond
covalent
ionic bonds are typically made from elements on which side of the table
far right and far left
covalent bonds have low, medium, or high electronegativity
medium
elements with medium electronegativity do what with electrons
share them
polarity in covalent bonds is determined by
differences in electronegativity and symmetry
non polar covalent bonds mean electrons are
shared equally
polar covalent bonds mean electrons are
not shared equally
larger molecular bonds (3 steps) 6-12 atoms means polar
see which elements are bonded, assess individual bonds, add partial charges
