Chapter: Atom
Author's Note: Several atomic models were proposed from as early as the year 1803 to understand the structure of an atom. These models continued to evolve until scientists could finally place the electrons in various energy levels outside the nucleus and the proton and neutron inside the nucleus of an atom, thereby solving the jigsaw puzzle of the three main components that had eluded scientists for decades. This allowed them to correctly match an atom's properties to the various experimental observations.
In this chapter, we will learn about the power of protons and how these internuclear bits are mainly responsible for an element's identity and its special characteristics.
Power of Protons - Structure of an Atom
Changing the number of protons alters an atom's identity, resulting in a completely different element. For example, one proton is a Hydrogen atom, whereas 2 protons are Helium, 3 protons are Lithium, and so on.
The proton identity manifests in each element to have its own unique characteristics. For example, a bicycle pedal made of atoms with 12 protons......
......
These protons, along with neutrons, are present inside the nucleus, determining the element's identity. The electrons, located outside the nucleus, control how that element behaves.
Nature of subatomic particles
The proton is positively charged, the neutron is uncharged, and the electron is negatively charged, together forming an electrically neutral atom.......
