Question

in bohr's atomic theory when electron moves from one energy level to another energy level more distant from the nucleus energy is emitted right?

Answer 1

other way around. In the bohr model, close orbits are low energy orbits, and distant orbits are high energy orbits. In order to jump from a close to a distant orbit, the electron must gain energy. Energy is released when it falls back down a gain

Answer 2

ohhh so energy is emitted when it goes nearer to nucleus then absorb when it goes away from the nucleus?

Answer 3

yes

Answer 4

i get that they need to absorb to jump to a distant orbit...but why do they release energy when they go near the nucleus?

Answer 5

because the nucleus contains a big energy and they need to balance?

Answer 6

each level "has" a certain energy content. An electron can't exist on a level if it has a different energy than the level allows. If an electron at a high orbit doesn't lose some of its energy, it can't fall down to the lower ones. The energy released will always be equal to the difference between the 2 levels.

Answer 7

ohhh that's where the -r (1/n^2 - 1/m^2) thingy comes in right? thanks!!

Answer 8

right
