An atom is the basic unit of matter, made up of a nucleus containing protons and neutrons, surrounded by electrons in a cloud-like structure.
An atom has a central nucleus made up of positively charged protons and neutral neutrons, surrounded by negatively charged electrons in energy levels or shells.
Electrons are negatively charged particles that orbit the nucleus of an atom. They are responsible for the chemical and physical properties of an element and are involved in the formation of chemical bonds.
The nucleus is the central part of an atom that contains positively charged protons and neutral neutrons. It is responsible for the mass of the atom and plays a crucial role in determining the chemical properties of an element.
The vacuum, or empty space, between the electron cloud and the nucleus is essential for the stability of the atom. Without it, the negatively charged electrons would be attracted to the positively charged nucleus, causing the atom to collapse.
