Question

The energy of the electron in a hydrogen atom has a negative sigh for all possible orbits because
A) when the electron is attracted by the nucleus and is present in orbit n, the energy is emitted and it's energy is lowered.
B) when the electron is attracted by nucleus and is present in orbit n, the energy is absorbed and it's energy is increased.
C) when the electron is repelled by nucleus, the energy is released and it's energy is lowered.
D) None of these. ​

Answer 1

Answer:

The answer is A.

Explanation:

The energy of the electron in a hydrogen atom has a negative sign for all possible orbits. This negative sign means that the energy of the electron in the atom is lower than the energy of a free electron at rest. ... Thus it is assigned the energy value of zero
