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. 7.3 in your textbook. How atoms combine. Atoms with a full valence shell are very stable . Only the Noble gases are considered stable and therefore unreactive. Elements that have unfilled valence shells combine with other elements. 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.. At the end of this lesson, you need to draw . a diagram for each model showing the evolution of atomic theory:. ". Plum-Pudding" Model. Rutherford . Atom. Rutherford-Bohr . Atom. Charge-Cloud .

Navigating the Periodic Table. 2.4 The . 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.. Unit 3. Biochemistry. Kasprowicz. /Squires. Topic 1: Matter . . anything that has . MASS. and . TAKES UP SPACE . (has volume). Examples:.

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). 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. 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..
