Just look into some solid-state physics books..all are explained there..

Sorry, probably didn't tell you the following:
- I am not in High School yet, therefore it is hard to obtain these books due to the library reserving them for actual High school students ( you need to provide proof your a high school student in order to check them out.
Some elements, such as metals, have a high number of free electrons in their outermost energy level. These electrons are able to move freely through the material, allowing it to conduct electricity.
An element is magnetic because it has unpaired electrons in its outermost energy level. These electrons create a magnetic field when they spin, causing the element to be attracted to magnets.
Elements that are not conductors or magnetic typically have a full outer energy level, meaning all of their electrons are paired and do not create a magnetic field or allow for the flow of electricity.
Yes, some elements, such as iron, are both good conductors of electricity and magnetic. This is because they have both unpaired electrons and a high number of free electrons in their outer energy level.
The number of electrons in an element's outer energy level and whether or not they are paired or unpaired determines its conductivity and magnetism. Elements with a high number of free electrons and unpaired electrons are more likely to be conductors and magnetic, while those with a full outer energy level are not.
