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. 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 . Model. Section 4.2. Objectives. State the three . subparticles. of atoms. State the charges of the . subparticles. Describe the composition of an atom. Atom. Fundamental particles which make up matter. The smallest particle of an element that retains (keeps) its identity in a chemical reaction.

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.. . are the smallest components of nature. with the properties of a given substance.. Electrons. (negative charge). Protons. . (positive charge). Neutrons. . (no charge). For any given element:. Atomic Number . There are about 100 different types of atoms. An element is a substance which contains only one type of atom. Atoms. Atoms. The Periodic Table. The Periodic Table. Element, Compound, Mixture. Element, Compound, Mixture. Essential Questions:. What is. . the basic structure of atoms? . How is an atom’s mass calculated? . Which subatomic particles are electrically charged?. .. Essential Questions:. 4. Where are the three main subatomic particles located?. Atoms. . are the smallest unit of matter. . Matter. . is anything that has mass and takes up space. . A . ball is matter, water is matter, even the air you breathe is matter!. What is an atom. ? (cont.). 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. The structure of atoms dictate their properties. How atoms combine dictate what we see in the many . minerals. in nature. . New technologies allow us to peer ever closer at the minute structures of minerals, down to the scale of individual 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..
