In a collision between an electron and a hydrogen atom, it is useful to select both objects as the system because which of these:

1
The total momentum of the system does not change during the collision.

During the time interval just before to just after the collision, external forces are negligible.

The kinetic energy of a two-object system is nearly zero.

The sum of the final kinetic energies must equal the sum of the initial kinetic energies for a two-object system.

The forces the objects exert on each other are internal to the system and don't change the total momentum of the system

Both hydrogen and electron are selected as the system because the  total momentum of the system does not change during the collision.

The term "momentum" refers to the product of mass and velocity. According to the law of conservation of momentum. The total momentum of colliding bodies is constant. Hence;

  • Momentum before collision and
  • Momentum after collision

must be constant.

Therefore, both hydrogen and electron are selected as the system because the total momentum of the system does not change during the collision.
