What is Matter Made Of?

Matter is made up of particles, including atoms and molecules. Atoms are the smallest units of matter, and they are made up of even smaller particles called protons, neutrons, and electrons. Protons and neutrons are located in the nucleus of an atom, while electrons orbit the nucleus.

The arrangement of these particles determines the properties of the atom and the type of matter it makes up. For example, atoms with different numbers of protons and electrons will have different properties and will be classified as different elements. When atoms combine with each other, they form molecules, which are the building blocks of matter.

The properties of matter, such as its density, mass, and state (solid, liquid, or gas), are determined by the arrangement and motion of its atoms and molecules. For example, a solid has a fixed shape and volume because its atoms are tightly packed together and do not move around much. A liquid, on the other hand, has a fixed volume but can take the shape of its container because its atoms are more loosely packed and can move around.

In summary, matter is made up of particles, including atoms and molecules, which are held together by various forces. The arrangement and motion of these particles determine the properties of matter.
