November 30th Warm-up Week of 28 to 2 (textbook page 63)
Write the whole question What is an compound? And what is an example of an compound? Key: 5 4 3 1 2
2
Classifying Matter: Elements, Compounds, and Molecules
3
Elements Elements are substances made of a single type of atom
Represented by a symbol. Upper case letter or an Upper and lower case put together Example: C (Carbon) or Ca (Calcium)
4
Elements – Let’s try…. Examples of elements are: ________
5
H2O NaCl CO2 Compounds Represented by chemical formulas
Compounds are made from two or more different elements joined chemically Represented by chemical formulas H20 (Water) – 2 hydrogen and 1 Oxygen CO2 (carbon dioxide) – 1 Carbon and 2 Oxygen C6H12O6 (glucose) – 6 Carbon, 12 Hydrogen, and 6 Oxygen. Can only be separated by chemical means, not physically NaCl CO2
6
Organic Compounds Any chemical compound whose molecule contains carbon
Carbon is usually accompanied by one or more of the (CHONPS)* elements. Other elements (CHONPS)* C: Carbon H: Hydrogen O: Oxygen N: Nitrogen P: Phosphorus S: Sulfur
7
Your turn….. What is the difference between an element and a compound?
The difference between an element and a compound is ____________________ ______________________________.
8
Your turn….. Which of the following compounds are organic?
H20 (Water) – 2 hydrogen and 1 oxygen NaCl (Salt) – 1 sodium and 1 chlorine C6H12O6 (glucose) – 6 carbon, 12 hydrogen, and 6 oxygen.
9
Molecule Two or more atoms bonded together
Can be the same element or different elements Examples: H2O H2 NaCl O2
10
Your turn…. What is the difference between a compound and a molecule?
The difference between a compound and a molecule is _______________ ______________________________.
11
Can you identify the following?
You will be shown a series of photos. Tell if each photo represents an item composed of an element, compound, or molecule. Review: An element contains just one type of atom. A compound contains two or more different atoms joined together. A molecule contains two or more atoms combined chemically that can be the same or different elements
