Electron Flow Theory Part 1

Where does a solid understanding of electricity begin?

At the atomic level

What are atoms?

The smallest particles that elements can be broken into and still retain the properties of that element.

What is matter composed of?

Atoms

An atom is itself broken into smaller components called:

Subatomic Particles

What are the two subatomic particles found within the nucleus?

Protons and Neutrons

What do Protons have?

A Positive Charge

What do Neutrons have?

No electric charge, they are neutral

The nucleus is the heaviest part of the atom and accounts for:

The majority of the atom’s mass

Electrons, the third type of subatomic particle are in motion:

Around the nucleus and have a negative charge

For a neutral atom, there is:

One electron for each proton that resides in the nucleus

From a static shock to a lightning strike, all electricity is:

The movement of Electrons

The electrons occupy various energy levels around the nucleus, known as:

Shells

What happens each time one shell becomes full:

A new one begins

The Outer shell of an atom is known as its:

Valence Shell

The number of electrons that reside in the valence shell are:

What determines whether an element is a conductor, a semiconductor, or an insulator

In many elements, the valence shell holds a maximum of:

Eight Electrons
