Question

what does the negative electronic energy for hydrogen atom mean???????

Answer 1

electronic energy? what is that?

Answer 2

hey god ....heena page no.44 ncert class 11

Answer 3

the electron's total mechanical energy is negative- this must be what you mean.

Answer 4

srry for calling u dat its only words ok actaully ncert mis dat word it mean electric potential evergy ok

Answer 5

Its in class 12 NCERt Physics. Modern Physics too. beautiful explanation check that out.

Answer 6

now negative sign iss there only to show direction ok

Answer 7

@apoorvk in which page?

Answer 8

lol its chemistry topic

Answer 9

yea but thi equation is used in physsc as well :)

Answer 10

energy in that case u ca say they are trying to determine exo or endo by showing sign

Answer 11

hey god ..........kya bol rhi ho yr sb glt hai.... there no concept of exo ar endo okk

Answer 12

listen just giving advice if they say abu energy and show sign den they are rying to determine exo or endo reation ok

Answer 13

*trying=rying

Answer 14

and nw coming to ur qn i m not sure but i ll like to give my opinion as here u are aying -ve enrgy oh H atom mean when u seprate H molecules it will show exothermic reaction.. and amount of energy released is wwritten in for of negative to sshow exothermic reaction

Answer 15

wat u say @zbay ?

Answer 16

ok

Answer 17

rit arvi reply fast :P

Answer 18

u see we assume potential energy=0 at infinity distance from nucleus , so as we approach the nucleus the energy becomes negative.as a general case total energy of any bounded system is -ve

Answer 19

wow aarvind ya u totally right ...ya got....

Answer 20

ye and u can get a proof by bornhaber cycle that if u see total energy it will be laways negative becoz all endo in last turns in exo

Answer 21

arvi where r u from??????

Answer 22

which page? contents diary hoon kya main? khoj lo chup chaap. its somewhere in the first chapter of modern physics.

Answer 23

haha :P m to test kr ri ti mere bhai :D

Answer 24

look if u guys say abu bio ncert i read thoroughly but physc and chem ncert nah nvr dat much :P

Answer 25

Chem NCERT ghont lena. Koi hi central exam keliye very important. And, anyways NCERT is the BEST books for explaining concepts in a lucid manner, atleast for the basics/

Answer 26

yar mera bsaic clear h u knw dat or ncert m mene har page ni parha as mene sirf inpt thing hi parhi h or y sb qn k reason m us concepts de kti hu anywayss at the time of my xam paka dalugi aplogo ko pakka h :P

Answer 27

the energy of the electron in a hydrogen atom has a negative sign for all possible orbits. .this negative sigh means that the energy of the electtron in the atom is lower than the energy of a free is the at rest.a free electron at rest is an electron that is infintely at rest ias an relectron that is infnitely far away from the nucleus and is assigned the energy value =0

Answer 28

i got so many reason thnx neha :)

Answer 29

hhehehee bhai sch me ab jakr me smji...........the most negative value is given by N=1 which coressponds to the most stable orbit .we call this grouund state....is i m rit

Answer 30

potential energy graph for distance 'r' from nucleus.
