It also tells us that chlorine has 18 neutrons (35 - 17) and, as the number of electrons and protons are equal in a neutral atom, chlorine also has 17 electrons. The relative mass of a nucleus is ...

The “lead” of a pencil is actually made of a substance called graphite which is made of carbon atoms. The picture shows a close-up of one carbon atom. A hydrogen atom has one proton as the nucleus and ...

For example, a helium atom has an atomic mass of 4 ... there could be a particle with mass but no charge. He called it a neutron, and imagined it as a paired proton and electron.

That matters greatly to science: neutrons, the electrically neutral particles that sit alongside positively charged protons in the nucleus of an atom, can be used to probe the nature and structure ...
