This exercise examines the atomic structure of some elements. The three elements examined are;
- Iron - Fe-56
- Copper - Cu29
- Cerium - Xe 140.
See their analysis in the attached image.
What is a Atom?
An atom is a matter particle that specifies a chemical element uniquely. An atom is made up of a central nucleus and one or more negatively charged electrons.
The nucleus is positively charged and comprises one or more protons and neutrons, which are relatively heavy particles.
What is a Proton?
A proton is one of the three major particles that comprise an atom. Protons are present in the atom's nucleus.
This is a small, dense area in the atom's core. Protons have a positive electrical charge of one (+1) and a mass of one atomic mass unit (amu), or approximately 1.671027 kg.
What is a Neutron?
The neutron is a subatomic particle with the sign n or n0 that has a neutral charge and a slightly larger mass than a proton.
