Question

1. sort the cards under their proper heading, using the following descriptions: each circle represents an atom, and each different color represents a different kind of atom. if two atoms are touching, then they are bonded together. 2. sort the cards under their proper heading, then take a picture of your sorted cards with your ipad. 3. create a word document titled “ecm card sorting activity” then add your picture to it. your picture should have a caption titled something like “my first ecm sort.” 4. review your sorted cards and try to define each term on your own, then provide an example for each one. try your best not to look at the answers before you write your own. the more you try to figure out on your own, the better you will be able to do this better next time. type first definition examples a: element when atoms are small. b: compound c: mixture of elements d: mixture of compounds e: mixture of elements and compounds once you are done, fill it in.

Explanation:

• Element: A pure substance made of only one kind of atom. Example: Oxygen (O), where all atoms are of oxygen - type.
• Compound: A substance formed when two or more different kinds of atoms are chemically bonded together. Example: Water (H₂O), with hydrogen and oxygen atoms bonded.
• Mixture of Elements: A combination of two or more elements that are not chemically bonded. Example: Air which contains nitrogen, oxygen, and other elements not bonded to each other.
• Mixture of Compounds: A combination of two or more compounds. Example: Gasoline which is a mixture of various hydrocarbon compounds.
• Mixture of Elements and Compounds: A combination of elements and compounds. Example: Salt - water solution where salt (a compound) is mixed with water (a compound) and may also have dissolved oxygen (an element).

Answer:

• A: Element - A pure substance made of one kind of atom. Example: Oxygen.
• B: Compound - A substance with different atoms chemically bonded. Example: Water.
• C: Mixture of Elements - Elements combined without chemical bonding. Example: Air.
• D: Mixture of Compounds - Compounds combined together. Example: Gasoline.
• E: Mixture of Elements and Compounds - A combination of elements and compounds. Example: Salt - water solution.
