PPT-Atoms are Elemental

This is the TITLE of your notes Elements Elements are names given to specific atoms Each element has its own special characteristics and makeup Atoms Elements Compare the oxygen atom to the element box below Are there any similarities. 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. Physical Science. Chapter 4 – Section 2. State Standards.

Manufacturer shall state in the manufacturer’s environmental packaging requirement that elemental chlorine shall not be used as a bleaching agent to bleach virgin or recovered content fibers used in paper-based product packaging.. 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.. 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?. 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. —.  Mercury exists in elemental, inorganic, and organic forms, all of which may be toxic . .The . toxic manifestation depends on the form of exposure. This topic reviews sources of mercury exposure, the clinical manifestations, and the treatment and prevention of mercury toxicity.. Mystery Case 1. 4 year old boy. Previously healthy except for recurrent OM. 1 month of irritability – parents describe him as ‘withdrawn’. Night sweats for several weeks. The patient will not walk – states ‘my legs hurt’.
