In a metallic bond conductor what are the properties of the atoms?
Close Packed and have a crystal lattice
How many electrons are there on the valence orbit of a “good conductor”
4 or less
In a Semiconductor how many electrons do each atom have/ share?
8
What is the molecular structure of an Insulator?
Electrons tightly connected to the atoms and have more than four electrons in the valence orbit
How many protons and electrons are needed to create a neutral atom?
An equal amount of both protons and electrons
What are charged atoms said to be called?
Ionised
If an atom has fewer electrons than protons what charge does it have?
Positive Charge
