1
Q
what is the octet rule
A
atoms wanting to fill the outer shell with eight electrons
2
Q
what does electron poor mean
A
fewer than 8 electrons in the outer shell
3
Q
which elements can break the octet rule
A
atoms past the third period
4
Q
define formal charge
A
the difference between the number of valence electrons in the free atom and the number of electrons assigned to that atom in the lewis structure
5
Q
what is the equation for formal charge
A
number of electrons in the valence shell of the free atom - number of bonds in the atom - number of unshared electrons
6
Q
how to know you have the correct order of atoms in a molecule
A
the total number of formal charges (if they were modulus) is smaller or if there is a negative charge it is on the most electronegative atom
