Physically put, the electron has more energy the farther ( higher ) it is from the nucleus. Simple potential energy. PE = mgh
The farther an electron is from the nucleus, the greater its energy.
if an electron gains enough energy it jumps to a higher energy level. when this happens the atom is in an "excited" state.
Because if the radius is big, then the large distance affects the strenght of the electron with the nucleus. This also increases reactivity in non metals since it will be easier to take away the electron :)
No. The electrons nearest the nucleus have the lowest energy. The highestenergy electron is one that's out on its own, not bound to any nucleus.
An electron in a 2s orbital is on average closer to the nucleus.
Electrons are arranged around the atomic nucleus forming the electron clouds.

the electrons moving closer to the nucleus have lower energy level.why?AnswerWhen atoms absorb energy, electrons move into higher energy levels, and these electrons lose energy by emitting light when they return to lower energy levels.It's like a sea saw, you go up, you get energy, go back down, lose it.please recommend me :D
Do you mean the orbitals of electrons in atoms? If the electron is in an orbital closer to the nucleus, the energy attracting it to the nucleus is higher than if the electron orbit is further out. So it'll take more energy for an electron closer to the nucleus to jump to an orbital further away. But as the orbitals get further and further away, the energy required for them to make the jump will be less and less. Thank of it like a magnet pulling a steel marble in. When the steel marble is touching the magnet, it is harder to pull it away than if it is sitting 10 centimeters away from the magnet. And it will be harder to pull it away at 10 centimeters than at 20. The energy required for a quantum leap is inversely proportional to the distance from the nucleus.
Bromine has less valence shells than lead making the distance between its valence electron and its nucleus less than that of lead. This means that there is greater attraction between the nucleus and electron for bromine and it requires a higher ionisation energy to remove its electron.

The electron moving from a lower to a higher energy level equates to moving from a specific orbit 'r' to a specific orbit 'rr' that is farther from the nucleus.
Electrons orbit the nucleus of an atom in specific orbitals, a specific distance from the nucleus of the atom. A specific quanta of energy will knock the electron into a higher orbital. When the electron falls back into the lower orbital, it will give off that same specific quanta of energy. That is why lasers work.
That's actually not quite how it works, you're probably going by an outdated model of the atom. It is true that the probability of finding the electron at a larger distance from the nucleus tends to be larger for electrons with higher energy... the reason why should be fairly obvious: they have more energy to overcome the electromagnetic attraction between the (negative) electron and the (positive) nucleus.
