Complete and correctly sequence the steps for drawing Lewis Structures
WORD CHOICES: eight, one, valence, four, subtract, central, single, surrounding, higher, add, bonding, core, six, lower, more, multiple, less, two, pairs, Ione, octet, singles
A. Draw a ___ bond from each surrounding atom to the central atom, and ___ two valence electrons for each bond.
B. Determine the total number of ___ electrons available. For polyatomic ions, ___ one electron for each negative charge, or ___ one electron for each positive charge.
C. Place the atoms realtive to each other. Place the atom with ___ group number in the center because it has the ___ electronegativity. If atoms have the same group number, place the atom with the ___ period number in the center.
D. If the ___ atom still does not have a(n) ___, make a ___ bond by changing a ___ pait from on of the ___ atoms into a ___ pair to the ___ atom.
E. Distribute the remaining electrons as ___ so that each atom ends up with ___ electrons (or___for H). First place ___ pairs on ___ (___ electronegative) atoms to give each an ___. If any electrons remain, place them on the ___ atom. Then check that each atom has ___ electrons.

The sequence goes like this
B. Determine the total number of VALENCE electrons available. For polyatomic ions, ADD one electron for each negative charge, or SUBSTRACT one electron for each positive charge.
C. Place the atoms realtive to each other. Place the atom with LOWER group number in the center because it has the LOWER electronegativity. If atoms have the same group number, place the atom with the HIGHER period number in the center.
A. Draw a SINGLE bond from each surrounding atom to the central atom, and SUBSTRACT two valence electrons for each bond.
E. Distribute the remaining electrons as PAIRS so that each atom ends up with EIGHT electrons (or 2 for H). First place LONE pairs on SORROUNDING (MORE electronegative) atoms to give each an OCTET. If any electrons remain, place them on the CENTRAL atom. Then check that each atom has EIGHT electrons.
D. If the CENTRAL atom still does not have a(n) OCTET , make a MULTIPLE bond by changing a LONE pair from on of the SORROUNDING atoms into a BONDING pair to the CENTRAL atom.
