Human Body Earths Crust

Why do you think the elements most common in the human body are not the same as the elements most common in the Earths crust?Living and non-living things have different make-ups and need.

What are the rules for writing chemical symbols?The first letter in a symbol always begins with a capital letter.If the symbol is composed of two or three letters, the second and third letters are written in lower case.Letters are always printed, not written in cursive.

What is an element?An element is a pure substance that cannot be broken down into simpler substances. It contains only one type of atom.The use of symbols on the periodic table is to represent the elements that make up all matter.

Copper = Cu

Iron = Fe

Salt = Sodium ChlorideNaClWhy isnt NaCl on the periodic table?Compound Any substance made by chemically combining 2 or more elements.

Which of the substances involved in photosynthesis are elements? PhotosynthesisWhich of the substances are compounds? Which of the substances are molecules?

Cellular RespirationWhich of the substances involved in Cellular respiration are elements? Which of the substances are compounds?

Which of the substances are molecules?

How are the processes similar?

What are Organic Compounds?An organic compound is made up of carbon atoms bonded to atoms of other elements. Examples are carbohydrates, proteins, lipids, and nucleic acids.
