Elements, Compounds, and Mixtures

What is the difference between elements, compounds, and mixtures?

18 comments:

  1. Elements are made up of only one kind of atom,compounds are made up of 2 or more atoms chemically combined and mixtures are 2 or more atoms that are not chemically combined

  2. Elements are a pure substance, compounds are are a combinations of 2 of more elements that are combined by chemically, and mixtures are 2 or more elements that are combined physically; the elements that make them up still retain their original properties.

  3. The difference between a compound, mixture and, element is...
    ELEMENT: containes only one type of atom, can be found on the periodic table.
    COMPOUND: containes two or more kinds of atoms that are chemically combined.
    MIXTURE: containes two or more kinds of elements or compounds that are NOT chemically combined.

  4. Elements are one type of atom , Compounds are two or more atoms chemically combined, and Mixtures are two or more atoms not chemically combined.

  5. Elements is the actual pure substance, not a compound or a mixture, and a mixture is just a few elements mixed together not chemically combined (an example in full scale with us, cereal and milk, they are mixed, but you can separate them) mixtures can be separated. Compounds are 2 or more elements that are chemically combined with each other.

  6. A element is a pure substance with only one TYPE of atom. Examples are Hydrogen (H), Helium (He) and Neon (Ne). A compound is substance with two or more elements chemically combined. Examples are salt (NaCl) and water (H20). A mixture is two or more substances NOT chemically combined. The substances also keep their original properties. Examples are salt water, fruit salad and garbage.

  7. Elements are only made up of one type of atom. Elements are found on the Periodic Table of Elements. Compounds are 2 or more kinds of atoms chemically combined. A mixture is 2 or more atoms that is not chemically combined.

  8. The difference between element, compounds, and mixtures is that elements are made up of one atom. Compounds are chemically combined and are bonded and mixtures are not chemically combined or bonded.

  9. elements are one type of atom, compounds are two or more types of atoms chemicali combined, mixtures are two or more types of atoms not chemicali combined.

  10. Compound- two or more atoms chemically combined
    Element- is one atom that is on the periodic table
    Mixture-is 2 or more atoms not chemically combined

  11. A element is a pure subtance that only have 1 type of atom and it can be found on the periodic table.A compound have 2 or more atom and it is chemically combined.A mixture have 2 or more atom and it not chemically combined.

  12. The difference between elements,compound,and mixtures.Elements only have one type of atom. Compounds are 2 or more tipes of atomes chemichaly combined.Mixtures are 2 or more types of atomes that are not chemicaly combined

  13. An Element is a pure substance that cannot be broken down into anything smaller or more fine an example is gold.

    A compound is two or more elements chemicaly combined into another substance completely differentfrom the elements that it came from like salt or sugar.

    A mixture is two or more substancesthat are NOT chemicaly combined and can easily be separated like salad.

  14. A way to remember gold on the Periodic Table is "Au got gold"?

  15. Elements are made out of only one type of atom and can be found on the periodic table. Compounds contain 2 or more kinds of atoms that are chemically combined. Mixtures contain 2 or more elements or compounds that aren't chemically combined.

    They are different because they are made up of different amounts of elements.

  16. An element contains only one type of atom.(Ex: hydrogen, neon, iron, carbon) A compound is something with 2 or more kinds of atoms that ARE chemically combined. (Ex:Water, sugar, salt) A mixture is something with 2 or more kinds of atoms that are NOT chemically combined. (Ex: lemonade, sand, mud, air)

  17. Element
    An element is a pure substance that has only one atom and is found on the periodic table. Some elements are Zinc (Zn) Aluminium (Al) and also Iron (Fe).

    Comound
    A compound has two are more elements that are chemically combined. They can not be separated an else by chemicaly changed. So common examples are water and suger they are written by chemical foramulas like H2O.

    Mixture
    A mixture is two or more elemants that are NOT chemicaly combined. They can be separted by physical change. Some things that you find every day are Salad, Salt Water.

  18. A mixture is a couple of substances mixed together unchimicaly combined. A element is one substance. A compound is somthing chemically combined unable to unmix.
