Masses of Atoms, Ions, and Molecules. Non metals and Metalloids. A non metal is an element that is not a metal and does not have properties of metals. A metalloid is an element that is not a metal but it is similar to a metal.. Physical properties of nonmetals: Most nonmetals are poor conductors of electric current and heat. Solid nonmetals tend to be dull and brittle.. Matter. Chemistry: study of matter. Matter: any thing that has mass . 3 phases: solid, liquid, gas. Both living organisms and non living things are made up of matter. Atom. The atom is the basic unit of matter. 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.. Atoms are composed of protons, neutrons and electrons. These subatomic particles are charged….. Atoms make elements… Elements can’t be broken down into anything simpler. . Examples:. Carbon= C.

Jim Geiger. Cem 151. Atomic Theory of Matter. The theory of atoms:. Original to the Greeks. Leuccipus, Democritus and Lucretius. (Aristotle thought they were nuts). He believed that one could divide up a piece of matter an infinite number of times, that is, one never came up with a piece of matter that could not be further divided. He suggested that everything in the world was made up of some combination of four elements: earth, fire, water, and air. The elements were acted upon by the two forces of gravity and levity. Gravity was the tendency for earth and water to sink, and levity the tendency for air and fire to rise.. .
