A_{Z X} means ^{12}_6 C atom here? ^A_{Z+1} Y represent ^{12}_7 C ^+ ion am i right? to find the mass of ^{12}_6 C atom, the mass os 1 electron is subtracted ... why you said that the mass is subtracted to find the mass of ^{12}_5 C ^+ ion?
and i don't understand part 2 ) ,
why the mass defect is mx -(my-me) -me ?
the extra orbittin elc\ectron mass is already deducted in the last part -me am i right?
why the mass of elctron is deducted again in ( my-me )?
Homework Statement
from the physics fact in the photo, i know that the daughter nucleus is a positive ion...
but , referring to the part 2 , finding the mass loss in beta decay in terms of atomic mass , it says that A_(z+1) Y has extra one orbitting electron comapred to the parent nucleus.

Homework Statement
in the photo, the 23Na form 24Na Am i right?
if i am right, the mass of 23Na should decraese , and mass of 24Na should increase.
but why the solution provided is the mass of 24Na decreses and increases at the time of delta t ?? i can't understand

Homework Statement
in my book, it states that the reactivity of haloalkane in ascending order is C6H5CH(CL)CH3 <CH3)3 CCL <C6H5(CH3)2 CL ...
this involve formation of carbocation as intermediate , so i the lesser the partial negative charge on C atom during formation of carbocation ,the more...
Homework Statement
in the first photo , the direction of x-ray and the atomic plane are shown.
whereas for the 2nd photo , the
the direction of x-ray and the atomic plane are not shown... so i would assume the glancing angle = 0 . beacuse the atomic plane is parallel to the x-ray ...but in the...
alright, can you please look at the 2nd photo?
i can understand why the mass defect (for atomic mass) is mx -( my-me) -me , why not mx -( my+me) -me ?
before subtracting the mass of the 'extra orbitting electron' , why the mass defect is calculated by mx-my-me (just like nuclear mass at the...
##^A_{Z+1}Y## represent positive ion am i right? but not ##^A_{Z+1}Y^+## ... the product nuclei has Z+1 proton but the number of electrons remained the same... so for ##^A_{Z+1}Y## , it's a positive ion... am i right?
i knew this from the first photo.
Homework Statement
in the first photo of my note , it says that the product nucleus has Z electrons (not Z+1) electrons ,
whereas for the 2nd part of my note , it says that the atomic masses of the product nucleus( which has A nucelon mumber and Z+1 proton number) , it has one extra orbitting...
hi, When testing the hypothesis, you are comparing the cumulative probability of this sample (at least 8 people), against the claim
why the author doesn't say 'the investigator selects a random smaple of 22 people and at most 8 people agree to vote for him ' instead?
Homework Statement
Given that 8 person vote for Mr Tan , i can't understand why the probability is sum of 0 people vote for him until 8 people vote for him. Why not the probability = 22c8 ( (0.6)^8 )( (0.4)^14) ?
