The Inner Workings of Cobalt: Electrons, Protons, and Neutrons

At its most basic level, cobalt consists of electrons, protons and neutrons: the building blocks of matter. With regards to cobalt:

• Electrons: Cobalt has twenty seven electrons orbiting its nucleus in specific layers or shells. These negatively charged particles determine how the atom behaves chemically – or rather its reactivity. By arranging its electrons in different ways cobalt is made able to form a variety of compounds and take part in creating alloys.
• Protons: The nucleus of an atom of cobalt contains twenty seven protons which are positively charged particles; they give cobalts atomic number meaning without them it wouldn’t be what we call ‘cobalt’. This positive charge attracts negatively charged electrons thus holding them in their orbits around the nucleus tightly.
• Neutrons: Neutrons are neutral subatomic particles that contain no electric charge; they help stabilize nuclei by adding mass so that protons don’t repel each other due to like charges (neutrons act as glue). For example, stable isotopes like Co-59 have 32 neutrons more than 27 protons found in one atom making up this element called “cobalt”.

These few words about particle behavior can lead us into some facts on physical and chemical properties such as magnetism or strength but also reactivity too.The knowledge gained from these studies could pave way for new medical treatments among other applications where durability is required hence leading to innovation within various industries dealing with this metal called ‘cobalt’.
