A small discrete unit of energy is called a quantum of energy. The definition of quantum is a discrete quantity of energy proportional in magnitude to the frequency of the radiation that it represents.

A particle of light. Or, in general, of an electromagnetic wave.

Temperature is generally considered to be continuous. However, at the particle level of physics ,energy is believed to be made of discrete particles, so in actuality temperature may not be continuous but jumps in quantum amounts when temperature changes.
Yes, electrons can have different amounts of energy. In quantum mechanical systems where any particle (not just electrons) are bound, they can only acquire discrete amounts of energy called energy levels. Adding energy to an electron in an atom might cause it to jump to a higher energy level and is then said to be in an excited state; if it were to fall to a lower level it would give up a discrete amount of energy equal to the difference in energy between the two states.

The enrgy is always lost or gained in only the definite amount that is called as discrete or packet energy.
While some forms of energy can be considered as either particle or wave, steam is not one of those. The energy of steam comes from it expansion. There is no steam energy particle.
