Chemistry, Earth history, infecteases disease

chemistry- 8.p.1- Understand the properties of matter and changes that occur when matter interacts in an open and closed container.

-physical and chemical properties- The physical structure of an organisms, that is observed during a reaction.

-physical and chemical change- The changes matter undergoes are classified as either physical changes or chemical changes.

-elements, compounds, and mixtures- made of one type of atom, made of 2 or more atoms, and combination of 2 or more pure.

-periodic table- number of protons and elections in an atoms of one elements.

*Groups and periods- periodic table

*Metals, non-metals, metalloids- The metalloids separate the metals and nonmetals on a periodic table.

*Atomic number, atomic mass, protons, neutrons, and Electrons-

-law of conservation of mass- states that any system closed to all transfers of matter and energy.


Earth History
