In class Obj. I will be able to identify the common elements, know the difference between a compound and an element, and know the majority of the solid earth, oceans, living matter, and atmosphere are comprised of these elements.
Vocabulary ◦ Element ◦ Compound ◦ Pure substance ◦ Chemical symbol ◦ Bond ◦ Periodic table of elements ◦ Living matter ◦ Solid earth ◦ Oceans ◦ Atmosphere ◦ precipitate
@ home Learn the names and symbols for the common elements ◦ Si- Silicon ◦ O- Oxygen ◦ C- Carbon ◦ H- Hydrogen ◦ N- Nitrogen ◦ P- Phosphorus ◦ Cl- Chlorine ◦ Na- Sodium ◦ Ca- Calcium ◦ He- Helium ◦ S- Sulfur Review vocabulary terms and definitions
Notes Element- A substance that cannot be broken down chemically into simpler substances. Compound- A substance made by chemically combining two or more elements. Pure Substance- the same throughout the matter. Chemical symbol- the letter(s) that represents each element on the periodic table. Bond- identified as what holds atoms together. Periodic table of elements- an arrangement of the elements according to their properties.
Notes Living matter- cells from living matter are made of Carbon bonded with other elements. Solid earth- Oxygen and Silicon are the main elements that make the rock and minerals of the Earth’s crust. Oceans- Water is Hydrogen and Oxygen. Atmosphere- A mixture of Nitrogen and Oxygen with small amounts of other gases. Precipitate- The solid that is formed as a result of a precipitation reaction.
