MATTER IS MADE UP OF TINY PARTICLES CALLED ATOMS BECAUSE MATTER IS MADE UP OF MOLUCLES AND MOLUCLES ARE MADE UP OF ATOMS

Atoms are the correct answer to the question. Let's understand why atoms are the tiny particles that make up matter.

Atoms and their structure:
- Atoms are the basic building blocks of matter. They are incredibly small particles that cannot be seen with the naked eye.
- Atoms are made up of even smaller particles called protons, neutrons, and electrons.
- Protons have a positive charge, neutrons have no charge, and electrons have a negative charge.
- Protons and neutrons are located in the center of the atom, called the nucleus, while electrons orbit around the nucleus in specific energy levels.

Properties of atoms:
- Atoms are very tiny, with a typical size of about one ten-billionth of a meter.
- Each element in the periodic table is made up of a unique type of atom.
- Atoms of different elements have different numbers of protons, neutrons, and electrons.
- The number of protons in an atom determines its atomic number and defines the element.
- Atoms are neutral overall because the number of protons equals the number of electrons.

Formation of matter:
- Matter is anything that has mass and occupies space.
- Matter can exist in different forms such as solid, liquid, or gas.
- Matter is made up of atoms that combine to form molecules or ions.
- Molecules are formed when two or more atoms bond together. For example, water (H2O) is a molecule made up of two hydrogen atoms and one oxygen atom.
- Ions are formed when atoms gain or lose electrons and become charged particles. For example, sodium (Na) loses an electron to become a positively charged ion (Na+).

Conclusion:
Atoms are the tiny particles that make up matter. They are made up of protons, neutrons, and electrons and form the basis of all elements in the periodic table. Atoms combine to form molecules or ions, which then make up different forms of matter. Understanding the structure and properties of atoms is crucial in understanding the nature of matter.
