10/11 notes

Question 1

what does the general curve work for

Answer 1

pretty much any type of atomic or molecular interactions

Question 2

why does repulsion occur

Answer 2

pauli exclusion principle (different than electron-electron repulsion)

Question 3

where is the most stable on the general curve

Answer 3

bottom of energy well, energy minimum

Question 4

what does it take to break a bond

Answer 4

cost energy, change in energy is posotive

Question 5

what is released when a bond is made

Answer 5

E is released and change in energy is negative

Question 6

bond energy

Answer 6

of the amount of energy needed to break apart one mole of covalently bonded gases

Question 7

bond distance

Answer 7

the average distance between nuclei of two bonded atoms in a molecule.

Question 8

Answer 8

metallic bonds ->metallic compounds

Question 9

nonmetal + nonmetals make what type of bond

Answer 9

covalent bonds ->covalent compounds

destabilization/costs

Answer 12

first IE of Na

Question 13

stabilization/gain

Answer 13

electron affinity of Cl
