Electrons are very important in the world of electronics. The very small particles can stream through wires and circuits, creating currents of electricity. The electrons move from negatively charged parts to positively charged ones. ... When the electrons move, the current can flow through the system.

What is an electron and why are they important?

The electrons that occupy the outer most shell of an atom are called valence electrons. They are important because they determine how an atom will react. By writing an electron configuration, You'll be able to see how many electrons occupy the highest energy level. ... Electrons.

Why is electron matter?

In quantum mechanics, the concept of a point particle is complicated by the Heisenberg uncertainty principle, because even an elementary particle, with no internal structure, occupies a nonzero volume. Therefore, electrons have mass and volume, hence electrons are matter.
