Periodic Table. Antoine Lavoisier. Law of Conservation of Matter: matter can not be destroyed nor created.. Dalton’s Atomic Theory. All elements are composed of atoms.. Atoms of the same element are identical. Atoms of any one element are different than atoms of another element.. ASTR 101. Prof. Dave Hanes. The . Pessimist. [writing in 1835]. . On the subject of stars, all investigations which are not ultimately reducible to simple visual observations are…necessarily denied to us… We shall never be able by any means to study their chemical . 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.. . By: . Courtney Parham, . Baylee. Travers, . Kody.

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. Protection of the Brain. Nervous tissue is soft and easily injured. Several systems are in place to protect the brain.. Meninges. The Meninges consist of three connective tissue membranes that cover the organs of the CNS. They have several functions:. Energy Levels. Electrons are arranged in different levels with in the electron cloud. There is a specific rule as to how many electrons can fit in each level of an electron.. In order to calculate how many electrons an energy level will have use the formula 2n^2 where n= energy level. Atoms and the Periodic Table Atomic Structure ATOM: the smallest particle that has the properties of an element. From the early Greek concept of the atom to the modern atomic theory, scientists have built on and modified existing models of the atom. and Ions. 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.. Dr John Mitchell. ID1004: Approaches to Reality. For Years People Wondered …. What is the World Made of?. What is Matter?. I. s Water Made of the Same Stuff as Rock?. Is Matter Continuous?. Is Matter Continuous?. For Example: If you have a piece of gold and cut it into smaller and . smaller pieces, . you would eventually reach a point where you couldn’t cut the gold up any smaller. That smallest piece would be an atom of gold.. misericordia. e. , in . . Sarnano (MC), . . 1494 . La . Mater . Misericordiae. nella pietà e nell’arte . Mater . misericordiae. Niardo (. Bs. ) . Eremo di san Giorgio. a. ffresco del XV secolo. Mater . The Sun produces energy in this manner.. Hydrogen bombs use this process.. Much more energy per gram is released by fusion than is by fission.. Fusion reactions create no radioactive waste . Unfortunately it is much harder to start and control a self sustaining reaction..
