At the Completion of this Unit, Students will be able to. :. List the major chemical elements in cells and know their chemical symbols and explain why they are essential to life (i.e. carbon, hydrogen, oxygen, nitrogen, phosphorus, sulfur, potassium, and trace elements). Matter and Atoms. Matter is anything that takes up space and has mass. There are 4 phases of matter solid, liquid, gas, and plasma.. All matter is made of atoms.. Atoms are the building blocks of matter, sort of how bricks are the building blocks of houses.. Presented by Kesler Science. How are chemical formulas used to identify substances?. How do chemical formulas determine the number of atoms of each element using subscripts, coefficients, and parenthesis?. Development of the Atom. The Hellenic Market. Fire Water Earth Air. ~. ~.

Section 5-1 History of the Periodic Table.  By 1860, more than 60 elements had been discovered, yet chemists had no way of organizing them or agreeing on basic properties of the element.. They can be joined together by . chemical bonds. From last lesson:. Atoms can have different numbers of protons, neutrons and electrons.. There are 118 different types of atoms.. They can be found on the periodic table of elements.. history. A 100,000-year-old ochre-processing workshop was found at . Blombos. Cave in South Africa. It indicates that early humans had an elementary knowledge of chemistry. Paintings drawn by early humans consisting of early humans mixing animal blood with other liquids found on cave walls also indicate a small knowledge of chemistry.
