PPT-Mater, Energy, Elements, and Atoms

By Mark Noah and Katie Definitions Matter Anything that occupies soace and has mass Energy the ability to do work Elements any of the building blocks of matter oxygen hydrogen carbon for example. Bonding. p. 144-156. Remember….. There are two kinds of pure substances. Elements. Compounds. Elements. Substance that cannot be separated or broken down into simpler substances by chemical means.. Bio “Life” . +. . Chemistry “Chemical Reactions”. . =. The study of chemical reactions in living things. . Why Biochemistry?. One characteristic of living things: life depends on . chemical reactions!. 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?. All matter is made of tiny indivisible solids. “. Atomos. ” = Indivisible. Plato. matter is made up of fire, water, and air. Their characteristics are due to the five solid shapes of the particles that make them.. Jennie L. Borders. Warm-Up Feb. 24. What did Rutherford discover?. What charge does a neutron have?. How many electrons can the first energy level hold?. Section 4.1 – Studying Atoms. Democritus. believed that all matter consisted of extremely . What is an element?. A element is a pure substance made of one type of atom. Elements are divided into metals and non-metals. Examples of non-metal elements include carbon, oxygen, hydrogen, and nitrogen. 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. Characteristics of Life Biology 1 APG 6 Characteristics Made of Cells - cells are the most basic unit of life, single cell organisms do exist Reproduce – offspring must be produced before an organism dies so the species can live on 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. Rock, wood, air, metal, water, and animals are all matter. Matter. Elements. The various forms of matter are composed of one or more chemical elements. . An . element. is a pure substance that cannot be broken down into other substances by chemical means. . 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.. 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.. 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..
