The chemical building block of the atomic structure
The Bohr model shows a simple model of the atomic structure. The atom has basic structure with just a central core. A nucleus containing the protons(positive charged) and neutrons(neutral).The atom is the smallest part of an that can retain the properties of the element. That atom can also be broken down in three subatomic particles that don't have the properties of that element.
The first subatomic particle are positive charged protons.
The second subatomic particle are neutral neutrons. Neutral meaning it is not positive nor negatively charged.
And lastly, the third subatomic particle are negative charged electrons.
Well if we look to the Bohr model to describe what an atom looks like. In the middle we have our protons and neutrons which are positively charged protons and the neutrons for the nucleus is made positively charged. Surrounding the nucleus in orbit so we have the electrons. Electrons are negatively charged as mentioned earlier and because the atom is overall electronically neutral the number of protons equals the number of electrons within an atom.
