The Role of Electrons
By Jessica Wade 8B
What are Electrons?
According to what are electrons (2010) "electrons are the subatomic particles that orbit the nucleus of an atom. They are generally negative in charge and are much smaller than the nucleus of the atom."
Electron Shells
Electrons are found in shells, which are numbered 1, 2, 3 and 4 and are named K, L, M and N. It is easy to image the electron shells by using a pea as the nucleus of the atom. The pea sits in the middle of a table tennis ball, whilst this all sits inside a tennis ball, which then sits inside a basketball then finally sits in a beach ball! Tiny ants are running fast on each of the balls, staying as far away as possible from the other ants. The ants represent the electrons always trying to get away from each other.

Showing the differences
The diagram shows what makes protons and electrons different, with a proton you have a positive charge and with an electron you have a negative charge.
