Question

If a H2 atom is supplied 15.8 eV of energy , the kinetic energy of the escaped electron is?

Answer 1

@experimentX

Answer 2

15.8 eV - 13.6 eV ... or something ... i forgot.
just google the ground state energy of H2 atom.

Answer 3

13.6 eV is the energy of H2 at ground state

Answer 4

well .. the KE is 2.2 eV ... just convert this in to Joules = 1/2 mv^2 ...

Answer 5

1eV = 1.6 * 10^-19 j

Answer 6

just do the usual stuff ... you have all info you need.

Answer 7

i got it thxx
