What are some examples of elements, atoms,compounds, mixtures, and molecule.
Thank you for helping me on this question
This is such a broad question.
Look on the periodic chart and pick out any of the 100+ elements. An atom is ONE of any given element, and some element combine with themselves to make molecules (H2, O2, N2 are example). Compounds are combination of elements, H2O is an example of a compound). Air is a mixture of gases, primarily nitrogen and oxygen (with about 1% Ar) plus minor amount of other gases.
thanks

Sure! I'd be happy to help you with examples of elements, atoms, compounds, mixtures, and molecules.
1. Elements: Elements are substances that cannot be broken down into simpler substances by chemical means. Some examples of elements are oxygen (O), carbon (C), hydrogen (H), and iron (Fe).
2. Atoms: Atoms are the building blocks of matter, and they are the smallest unit of an element that retains its chemical properties. For example, an oxygen atom (O) is the smallest unit of the element oxygen, and a carbon atom (C) is the smallest unit of the element carbon.
3. Compounds: Compounds are substances formed by the chemical combination of two or more elements in fixed proportions. Some examples of compounds include water (H2O), carbon dioxide (CO2), and sodium chloride (NaCl, or table salt).
4. Mixtures: Mixtures are substances made up of two or more elements or compounds that are physically combined, but not chemically bonded. Mixtures can be separated into their individual components through physical methods. Examples of mixtures include air (which is a mixture of nitrogen, oxygen, and other gases), saltwater (a mixture of salt and water), and sand (a mixture of small rock particles).
5. Molecules: Molecules are formed when two or more atoms are chemically bonded together. They can be composed of the same elements or different elements. For example, a water molecule (H2O) consists of two hydrogen atoms bonded to one oxygen atom.
To find examples, you can refer to the periodic table to identify elements. For compounds and their chemical formulas, you can search for commonly known examples, such as water or table salt. Mixtures can be found in everyday substances, while molecules can be identified by understanding how elements combine chemically to form different substances.
