Atoms, Molecules, Elements, and Compounds: Atoms Molecules Elements And Compounds Worksheet
Matter is made up of tiny particles called atoms, which combine to form molecules and compounds. These substances have different properties and play crucial roles in the world around us.
Elements, Atoms molecules elements and compounds worksheet
An element is a pure substance that cannot be broken down into simpler substances by chemical means. Each element is characterized by its unique atomic number, which represents the number of protons in its nucleus.
- Examples of elements include hydrogen (H), oxygen (O), and gold (Au).
- Elements can exist as individual atoms or combine with other elements to form compounds.
- Elements have specific chemical and physical properties that determine their behavior.
Atoms
An atom is the smallest unit of matter that retains the properties of an element. It consists of a nucleus, which contains protons and neutrons, and electrons that orbit the nucleus.
- Protons have a positive charge, while electrons have a negative charge.
- The number of protons in an atom determines its atomic number.
- Atoms can gain or lose electrons, becoming ions.
Molecules
A molecule is a group of atoms held together by chemical bonds. Molecules can be composed of atoms of the same element or different elements.
- Molecules are the basic units of compounds.
- Molecules have specific properties that depend on the atoms they contain.
- Molecules can interact with each other through chemical reactions.
Compounds
A compound is a substance composed of two or more different elements chemically combined in fixed proportions. Compounds have different properties from the elements they contain.
- Compounds are formed when atoms share or transfer electrons.
- Compounds can be ionic (formed by the attraction between ions) or covalent (formed by the sharing of electrons).
- Compounds have specific chemical and physical properties that determine their behavior.
FAQ Explained
What is the difference between an atom and a molecule?
An atom is the smallest unit of an element that retains the element’s chemical properties, while a molecule is a combination of two or more atoms held together by chemical bonds.
How are compounds formed?
Compounds are formed when atoms of different elements chemically combine in fixed proportions.
What are the properties of molecules?
Molecules exhibit specific properties, such as shape, polarity, and reactivity, which are determined by the arrangement and interactions of their constituent atoms.
