Formal Charge Flashcards
What does tetravalent mean?
carbon generally forms 4 bonds
What does trivalent mean?
nitrogen generally forms 3 bonds
What does divalent mean?
oxygen generally forms 2 bonds
What does monovalent mean?
hydrogens and halogens generally only form 1 bond
What is the formal charge?
charge of an atom in a molecule or polyatomic atom
What is the formal charge equation?
valence electrons - bonds - lone pair electrons = formal charge
What does it mean when an element is electronegative?
it is craving electrons, making it more unstable (likely to react)
What are polyatomic ions?
covalent molecules with a charge
What is a reaction?
reorganization of atoms
breaking/forming bonds
Do triple bonds or single bonds take more energy to break?
triple bonds
What happens when the epsilon is bigger?
attraction is also bigger
What is bond dissociation energy?
force required to separate into the corresponding atom
What is the collision model?
bonds broken/formed based on molecules that run into each other
What is activation energy?
minimum energy required for reaction to occur
What happens to collisions when there is increased heat?
there are more (effective) collisions
