Explanation for children:

Cells are the building blocks of our organs, and cells themselves consist of even smaller building blocks. Cells are the basic building blocks of biology, in other words, everything that lives is formed by cells. The smallest components we have discovered so far are atoms. They are the basic building blocks of everything. Everything that exists consists of atoms: us, our mobile phone, our bed, and so on. They once again consist of smaller units, one of which is the electron. Electrons are negatively charged and circle around the center of the atom. The charge of the electrons is very important for us, because it can conduct electricity so we can for example watch television in the evening.
