Answer:
Hello!
*I'll include the names here and the definitions and properties in the explanation since they are descriptive.
Three States of Matter:
- Solid
- Liquid
- Gas
Explanation:
Matter:
Anything that has mass and occupies space (volume) is called matter. Basically, matter (and energy) constitute all the phenomena in the universe.
Composition of Matter:
1. Atom:
An atom is the smallest component into which matter can be divided. It contains charged particles such as electrons, protons and neutrons. It is the basic building block of all substances.
2. Element:
An element is a chemical substance that cannot be broken down into its constituents by simple chemical processes. For example, copper (Cu)
3. Compound:
A chemical substance formed by the combination or bonding of two or more atoms or elements. For example, NaCl is a compound that contains the elements sodium and chlorine linked together by chemical bonds.
4. Physical Properties of Matter:
Properties that are physically observable and quantifiable. All properties that can be studied without changing the chemical constitution of matter. Following are some examples of physical properties:
- Melting point
- Boiling point
- Lustre
- Shape
- Conductivity
- Mass
- Volume
- Density
- Length
5. Chemical Properties of Matter:
Properties that demonstrate a substance's ability to form chemical bonds (undergo chemical reactions) with other substances. Chemical properties are only observable or measurable if the state or chemical composition of the substance is changed. Some examples are:
- Chemical stability
- Flammability
- Reactivity (with acids, oxygen, bases, etc.)
- Oxidation/Reduction
- Radioactivity
