What is Formal Charge?
500
What is P(F_6)^-?
500
The atom is more tightly held together meaning you need more energy to separate the two atoms
What is a shorter bond length?
500
Chemical Bonds can be thought of as always laying somewhere on a scale between a perfectly ionic situation and a perfectly covalent situation
What is the Continuum of Chemical bonds?
500
The ability of an atom in a molecule to attract the shared electrons in a covalent bond
What is electronegativity?
500
Calculated from the sum of the formal charges of each atom in the molecule
What is total charge?
