Multiple Choice

All matter is made up of...

• Mass

• Volume

• Atoms

​Electron

• ​The electron is most important because it is on the outside of the atom, so it can leave the atom to find a neutral charge.

• ​

• ​The number of electrons compared to protons & neutrons determines if the atom is positive or negative.

Poll

​Static electricity

• ​Static electricity occurs when there is a build-up of electrons in a material.

• ​Electrons build-up in insulators.

• ​

• When the charged insulator gets close to a conductor, it releases the electrons, causing a shock. ​
