Welcome to the Chemistry lesson 2.
The atomic structure.
An atom is the smallest particle of an element that takes part in a chemical reaction. Atoms of different elements react to form compounds. They do so due to the fact that atom exists.
There are particles in an atom called ๐ข๐พ๐ซ-๐ช๐ฝ๐ธ๐ถ๐ฒ๐ฌ ๐น๐ช๐ป๐ฝ๐ฒ๐ฌ๐ต๐ฎ๐ผ. These are protons and neutrons found at the centre of an atom-the nucleus, the other is the electrons found surrounding the nucleus.
The neutrons are neutrally charged subatomic particle of an atom. The protons are positively charged particles while the electrons are negatively charged particles. They are founding moving in their orbits called energy levels ( quantum shells).
The electrons at the outermost quantum she'll of an atom determine the chemical properties of an element.
With this, you have partially known what atom is made up of being electrons, protons and neutrons.
Therefore, next time, we will be talking about the periodic table
