Atom and its structure


I would say the definition of atom" as basic unit of matter; it can also called the building blocks of anything which exists in form". The central portion of an atom is known as the atomic nucleus. Atoms consist of protons, which carry positive charge, neutrons, which carry no electric charge.


 Protons are the positively charged particles, and electrons are negatively charged. Atoms make up matter and matter makes up the universe. 

Atoms get together to form molecules. Atoms are made of electrons and protons,When atoms of different elements come together, compound molecules are formed. As you might know, there are two types of compounds, ionic and covalent. The ions of ionic compounds are bound together due to the electrostatic forces between oppositely charged bodies.
