Fill in Hand Organizers as We Go! Write the definition (in your own words) for compound and mixture. Five examples of a compound – 1 on each finger. Five examples of a mixture – 1 on each finger.

Elements consists of only one kind of atom, cannot be broken down into a simpler type of matter by either physical or chemical means, and can exist as either atoms (e. g. argon) or molecules (e. g. , nitrogen). Each element is unique

Elements

Elements With over 100 elements, it is important to classify them in terms of their chemical properties (e. g. metal/non-metal). The elements are organized in the Periodic Table

Element Examples Elements and their atoms are represented by symbols. n n n n Argon, Ar Lead, Pb Gold, Au Aluminium, Al Oxygen, O Carbon, C Potassium, K This is the element Argon

Elements

Compounds consists of atoms of two or more different elements bonded together, can be broken down into a simpler type of matter (elements) by chemical means (but not by physical means), has properties that are different from the elements that it is made of.

Compounds

Compounds A compound is a substance formed when two or more elements are chemically joined. Water, salt, and sugar are examples of compounds. When the elements are joined, the atoms lose their individual properties and have different properties from the elements they are composed of. Water molecule

Compound Examples Sodium (Na) + Chlorine (Cl) = Sodium Chloride

Compounds Sugar – C 6 H 12 O 6 Caffeine- C 8 H 10 N 4 O 2 Water – H 2 O Carbon Dioxide – CO 2 Salt – Na. Cl

Compounds

Mixtures consists of two or more different elements and/or compounds physically intermingled, can be separated into its components by physical means, and often retains many of the properties of its components.

Salad anyone? Mixtures are two or more substances that are mixed together but not chemically joined. A good example of a mixture is a salad. There are tomatoes, lettuce, cucumbers, and salad dressing all mixed together. No chemical reactions occur between the vegetables and the dressing. You can separate each of the vegetables from each other.
