C and C : they are isotopes because same number of protons (6) but different number of neutrons (6 & 7)

1) C and C : they are isotopes because same number of protons (6) but different number of neutrons (6 & 7)

2) B and C : they are not isotopes because of different number of protons (5 & 6) and different number of neutrons (6 & 5)

Electrons are orbiting in several orbits

It shows the nucleus with the electron all revolving around it in several paths; (E1, E2, E3,..., E7). E1 is the ground state. If it jumps down a level is gives radiation, if it moves up a level it absorbs energy.
Delta E = E2 - E1 =
3 Limitations:
1) the model explains the hydrogen atom only
2) couldn’t explain why the electrons are stable and why they rotate like planets
3) uncertainty principle ( you can not pin point the exact location and speed at the same time with high accuracy)

Because the particles that are together , they are compressed and some of the mass turned into energy in air

# data[].attributes.body
Because the mass  converted to energy to hold the two nuclei

When they are together some of the mass turns into energy to hold together

Describe Bohr model of the atom? and point the limitations of this model.

Why the mass of the separated particles of a nucleus are greater than the mass of the nucleus itself?
