PPT-ELEMENTS AND ATOMS NOTES

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. All of the elements in a period have the same number of atomic orbitals. . Every element in the top row (the first period) has one orbital for its electrons. . All of the elements in the second row (the second period) have two orbitals for their electrons. It goes down the periodic table like that.. 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.. Heath Text. Ghost Notes:.

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. Unit 3. Biochemistry. Kasprowicz. /Squires. Topic 1: Matter . . anything that has . MASS. and . TAKES UP SPACE . (has volume). Examples:. Topic 1: Matter . Topic 1: Matter . . MASS. . is the amount of matter in an . 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?. Mr. . Polard. Physical Science. Section 1 . Structure of Matter. Vocabulary – Section 1. Matter. : . Anything that takes up space and has mass (pg72). Atom. : . A very small particle that makes up most kinds of matter and consists of smaller parts called protons, neutrons, and electrons (pg73). 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. 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. . Develop and use models to illustrate the structure of atoms, including the subatomic particles with their relative positions and charges.. Date. Essential Question(s). 1) . What is matter?. 2) . What is the basic structure of atoms?. 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..
