Atomic Structure: All matter in the universe is made up of atoms, which are the basic building blocks of matter. Atoms are composed of a small nucleus containing positively charged protons and neutrally charged neutrons, surrounded by a cloud of negatively charged electrons. Atomic Number: The number of protons in the nucleus of an atom is known as its atomic number. This number determines the chemical properties of an element. Molecule: A molecule is two or more atoms that are bonded together, forming a distinct substance with its own chemical properties.

The Bohr model of the atom was created by Nobel Prize-winning physicist Niels Bohr in 1913. An atom is made up of protons, neutrons, and electrons, but it's actually 99.9999999999% empty space. Neutrons have no electrical charge, but they are still attracted to protons due to the strong nuclear force.
