Unit 6.3 Types of Chemical reactions Most chemical reactions can be classified into one of five types of reactions. It depends on both the reactants used and the products formed. The possible chemical reactions are: 1. Coination Reaction or Synthesis Reaction
Bromine is a chemical element with the syol Br and atomic nuer 35. It is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly coloured gas. Its properties are thus intermediate between those of chlorine and iodine. Isolated independently by two chemists, Carl Jacob

Calcium (Ca) Arsenic (As) Nitrogen (N) Question 16 Of the three elements listed below, one is a metal, one is a nonmetal, and one is a metalloid. Identify which egory the three elements fall into. Silver (Ag) Antimony (Sb) Sulfur (S) Question 17 Of the
The Nonmetals There is a clear pattern in the chemistry of the main group metals: The main group metals are oxidized in all of their chemical reactions.These metals are oxidized when they react with nonmetal elements. Aluminum, for example, is oxidized by bromine.
In the formula: The nonmetal has fixed oxidation nuer: halogens -1, chalcogens -2, group of N -3, group of C -4, and the oxidation nuer of the metal can …

Metal, Nonmetal, or Metalloid? Lab Background Elements have unique physical and chemical properties, which make them useful for specific purposes in our everyday world. All known elements can be classified as metals, nonmetals, or metalloids according to
Question: A How Many Electrons Will Calcium Atoms Lose When The Metal Reacts With A Nonmetal? B. How Many Electrons Will Magnesium Atoms Lose When The Metal Reacts With A Nonmetal? C. How Many Electrons Will Strontium Atoms Lose When The
The metal has a silvery color, is rather hard, and is prepared by electrolysis of fused chloride and calcium fluoride (to lower the melting point). Chemically it is one of the alkaline earth elements; it readily forms a white coating of nitride in air, reacts with water, burns with a yellow-red flame.
Calcium Metal is available as disc, granules, ingot, pellets, pieces, powder, rod, wire, and sputtering target. Ultra high purity and high purity forms also include metal powder, submicron powder and nanoscale, quantum dots, targets for thin film deposition, pellets for evaporation and single crystal or polycrystalline forms.
