Atomic Structure and Conductivity

Front

Electron orbits

Back

The electron orbits are known as shells.

Front

Valence electrons and conductivity

Back

The number of valence electrons determines whether an element is an electrical conductor or insulator.

Front

Stability of atoms

Back

Any atom with more than 4 valence electrons is generally very stable, and that element will be an insulator.

Front

Insulators

Back

Materials with few free electrons in the outer shell.

Front

Copper atom composition

Back

29 protons and 29 electrons.

Front

Valence electron in copper

Back

Copper has one valence electron.

Front

First shell in a copper atom

Back

The innermost electron shell surrounding the nucleus.

Front

Examples of conductors

Back

Copper, silver, aluminium, gold, carbon, acid, alkaline or salt solutions.

Front

Electron flow direction

Back

Electron flow is from negative to positive.

Front

CY, SY flex cables

Back

Control cables and fixed installations/flex; can be used both indoors and outdoors
