An electron reaches a state of zero energy when it is at rest or in its ground state.
An electron reaches zero energy when it is at rest or in a state of lowest energy level, typically in an atom's ground state.
The mass of an electron is regarded as zero when it is at rest. The mass of an electron or any particle is calculated by using its momentum and its energy. The mass of an electron is related to its momentum which is zero when the electron is not moving. So when the electron is at rest its momentum is zero and thus its mass is zero. When an electron is moving its mass is no longer zero as its momentum is not zero. It is calculated by using the following equation: Mass = Energy / (Speed of Light)2The mass of an electron increases as its energy increases and it increases even more when it is moving at a higher speed. So when the electron is at rest and its momentum is zero its mass is also zero.
The electron does not lose its energy. The electron gets absorbed by the "wall" and the electron/energy becomes part of the "wall" system.

In the case of a free electron, there is no external force acting on the electron, so no work is done to displace it. Since potential energy is associated with work done in displacing an object against a force, the potential energy of a free electron is considered to be zero.
It becomes an anion.
No, because it is an acronym for "Zero Electron Kinetic Energy".
The kinetic energy of the car becomes zero when the car halts. If it halts on top of a hill, the energy changes to potential energy.
it becomes a positive ionit becomes a positive ion
actually total energy is the sum of potential energy and kinetic energy....potential energy= -2*kinetic energy . By using this relation you will get that sum of potential and kinetic energy is equal to the magnitude of kinetic energy and it is less than zero...hope this will be enough for you....
That's just the way it is defined. When talking about potential energy, what matters is differences in energy levels; any energy level can be arbitrarily defined as zero. However, it makes calculations simpler if you define the potential energy at an infinite distance as zero.
