Everything is made out of Atoms, such as Protons, Neurons, and Electrons, they make up everything, the water we drink, the air we breathe, and the things we use every day is made out of atoms, even though they all look completely different, but they are all made out of Proton, Electrons, and Neutrons, so what are they:
At the centre of an Atom, we have a Nucleus comprised of Protons and Neutrons, outside the Nucleus we have the "Neutron cloud", which is where you will find Electrons.
An Atom Neutron cloud can be 100,000 times larger than its Nucleus.
Protons have a positive charge of +1, while Electrons have a negative charge of -1, these charges cancel out as they are +1 and -1 charges, while the Neutron itself is neutral in charge.
We use the "Unified Atomic Mass Unit" as a way of saying the mass, the name of this form of measurement is usually shorted to the letter "U" so Protons and Neutrons have the mass of 1u, while Electrons have the mass of 0.0005u which makes them roughly 2000 times smaller than the Proton and Neutron, meaning all the mass from the Atom resides in the Nucleus.
Everything is an atom, but they are not the same, there are many different types of atoms, named Elements, each with their own special physical and chemical properties, many are commonly used, such as Oxygen, Carbon, Gold, and Silver.
Some might not be so familiar like Bismuth, Osmium and Xenon, a particular element is identified by the amount of Protons in its atom, known for its Atomic number or "Z", for example, Helium is atomic number 2, meaning every helium atom has two protons, and another is Iron its atomic number is 26 so they have 26 Proton, also the amount of Protons can also tell us how much
