Difference between electron affinity and electronegativity
Can anyone help explain the difference between electron affinity and electronegativity?
I'm kind of confuse about the two concepts and the trend of each.
Thanks a lot!

Question about HW1.45 and how to determine the incertainty of velocity [ENDORSED]
1.45 A bowling ball of mass 8.00 kg is rolled down a bowling alley lane at 5.00+/-5.0m/s. What's the minimum uncertainty in its positon? The student solution manual take 5m/s as the delta v. I feel confused because based on what i learned from the video, the delta v in this question should be double...

Re: Quantum World - Light
Etotal=W=p*t=40w*2.0s=80J
Ephoton=hc/λ
number of photon=Etotal/Ephoton
n(amount in mole)=number of photon/Avogado's constant
hope this can help you!
