Matter is made up of tiny particles called atoms and molecules. Atoms consist of a nucleus containing protons and neutrons, surrounded by electrons

. These atoms combine in various ways to form molecules, which are the building blocks of all matter

. At a deeper level, protons and neutrons themselves are made up of quarks, which are elementary particles

. Matter exists in different states-solid, liquid, gas, and others like plasma-depending on how these particles are arranged and interact

. In summary:

• Matter consists of atoms and molecules.
• Atoms are made of protons, neutrons, and electrons.
• Protons and neutrons are made of quarks.
• Matter occupies space and has mass.
• Matter exists in various states such as solids, liquids, gases, and plasma
